           Summary: .stringof performs semantic analysis
           Product: D
           Version: 1.012
          Platform: PC
        OS/Version: Windows
            Status: NEW
          Severity: normal
          Priority: P2
         Component: DMD
        AssignedTo: bugzilla digitalmars.com
        ReportedBy: clugdbug yahoo.com.au


According to the spec, "If applied to an expression, it is the source
representation of that expression. Semantic analysis is not done for that
expression."

But it seems that semantic analysis always occurs. This does not compile:
---
const char [] q = (1.2143*nonexistent).stringof;
---
By contrast, is() expressions also don't do semantic analysis, and they work
correctly:
static assert(!is(typeof(1.2143*nonexistent)));

The spec's .stringof example doesn't even compile:

import std.stdio;

struct Foo { }

enum Enum { RED }

typedef int myint;

void main()
{
    writefln((1+2).stringof);       // "1 + 2"
    writefln(Foo.stringof);         // "Foo"
    writefln(test.Foo.stringof);    // "test.Foo"
    writefln(int.stringof);         // "int"
    writefln((int*[5][]).stringof); // "int*[5][]"
    writefln(Enum.RED.stringof);    // "Enum.RED"
    writefln(test.myint.stringof);  // "test.myint"
    writefln((5).stringof);         // "5"
}

test.Foo.stringof and test.myint.stringof refuse to compile. Adding "module
test;" makes them compile, but then the results are not "test.Foo" and
"test.myint", but only "Foo" and "myint".
