            Bug ID: 37613
           Summary: Block literal example in Block language spec doesn't
                    compile
           Product: Documentation
           Version: trunk
          Hardware: All
                OS: All
            Status: NEW
          Severity: enhancement
          Priority: P
         Component: General docs

In the Clang Block language spec, section "Block Literal Expressions"
(https://clang.llvm.org/docs/BlockLanguageSpec.html#block-literal-expressions),
there is an example for block literal syntax that says the following:


Given:

typedef int (*pointerToFunctionThatReturnsIntWithCharArg)(char);
pointerToFunctionThatReturnsIntWithCharArg functionPointer;
^ pointerToFunctionThatReturnsIntWithCharArg (float x) { return
functionPointer; }

and:

^ int ((*)(float x))(char) { return functionPointer; }

are equivalent expressions, [...]


However, the second example, i.e.

^ int ((*)(float x))(char) { return functionPointer; }

does not compile in Clang. It produces the error "function cannot return
function type 'int (char)'".


The following expression does compile:

^ int (*(float x))(char) { return functionPointer; }

I am not sure whether it is the intended one.
