          Issue ID: 20417
           Summary: __traits(compiles) returns false result if expression
                    is not wrapped inside a lambda while typeof works
                    correctly
           Product: D
           Version: D2
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: P1
         Component: dmd
          Assignee: nobody puremagic.com
          Reporter: sahmi.soulaimane gmail.com

Test case:
```
struct A { ~this(); }
void f(A, int);
A a();
int i();

pragma(msg, __traits(compiles, { f(a, i); })); // true
pragma(msg, __traits(compiles, f(a, i))); // false

pragma(msg, __traits(compiles, typeof({ f(a, i); }))); // true
pragma(msg, __traits(compiles, typeof(f(a, i)))); // true
```

output:
---
true
false
true
true
---

expected:
---
true
true
true
true
---
