Description
The following new test case started failing after #59003 with the following stack trace
// RUN: %swift-ide-test -code-completion -source-filename %s -code-completion-token COMPLETE
func foo(closure: (String) -> Void) -> String? {
return nil
}
func test() {
if let key = foo(closure: { str in str.suffix(2) == #^COMPLETE^#Stack trace
Assertion failed: (func->isOperator() && "Lookup should only find operators"), function getTypeOfReference, file ConstraintSystem.cpp, line 1454.
PLEASE submit a bug report to https://bugs.llvm.org/ and include the crash backtrace.
