// Type maps expressions to their types, and for constant
// expressions, also their values. Invalid expressions are
// omitted.
//
// For (possibly parenthesized) identifiers denoting built-in
// functions, the recorded signatures are call-site specific:
// if the call result is not a constant, the recorded type is
// an argument-specific signature. Otherwise, the recorded type
// is invalid.
//
// The Types map does not record the type of every identifier,
// only those that appear where an arbitrary expression is
// permitted. For instance, the identifier f in a selector
// expression x.f is found only in the Selections map, the
// identifier z in a variable declaration 'var z int' is found
// only in the Defs map, and identifiers denoting packages in
// qualified identifiers are collected in the Uses map.

// Instantiate maps identifiers denoting generic types or functions to their
// type arguments and instantiated type.
//
// For example, Instantiate will map the identifier for 'T' in the type
// instantiation T[int, string] to the type arguments [int, string] and
// resulting instantiated *Named type. Given a generic function
// func F[A any](A), Instances will map the identifier for 'F' in the call
// expression F(int(1)) to the inferred type arguments [int], and resulting
// instantiated *Signature.
//
// Invariant: Instantiating Uses[id].Type() with Instances[id].TypeArgs
// results in an equivalent of Instances[id].Type.

// Def maps identifiers to the objects they define (including
// package names, dots "." of dot-imports, and blank "_" identifiers).
// For identifiers that do not denote objects (e.g., the package name
// in package clauses, or symbolic variables t in t := x.(type) of
// type switch headers), the corresponding objects are nil.
//
// For an embedded field, Def maps the field *Var it defines.
//
// Invariant: Defs[id] == nil || Defs[id].Pos() == id.Pos()
func (info gopRecorder) Def(id *ast.Ident, obj types.Object) {

// The following node and object types may appear:
//
//	node               declared object
//
//	*ast.ImportSpec    *PkgName for imports without renames
//	*ast.CaseClause    type-specific *Var for each type switch case clause (incl. default)
//	*ast.Field         anonymous parameter *Var (incl. unnamed results)

// to their corresponding selections.

// Scope maps ast.Nodes to the scopes they define. Package scopes are not
// associated with a specific node but with all files belonging to a package.
// Thus, the package scope can be found in the type-checked Package object.
// Scopes nest, with the Universe scope being the outermost scope, enclosing
// the package scope, which contains (one or more) files scopes, which enclose
// function scopes which in turn enclose statement and function literal scopes.
// Note that even though package-level functions are declared in the package
// scope, the function scopes are embedded in the file scope of the file
// containing the function declaration.
//
// The following node types may appear in Scopes:
//
//	*ast.File
//	*ast.FuncType
//	*ast.TypeSpec
//	*ast.BlockStmt
//	*ast.IfStmt
//	*ast.SwitchStmt
//	*ast.TypeSwitchStmt
//	*ast.CaseClause
//	*ast.CommClause
//	*ast.ForStmt
