see example below. with the last pragma commented out, the program works fine,
including 'enum er'.
with the pragma active, compilation fails. error message appears
at point of pragma processing, with the line number of the
enum er definition though.
...Error: variable _er_field_0,1,2 cannot be read at compile time

tested with DMD 2.063.2 win32 on home machine as well as with 2.063.2 64b and
latest git head via DPaste http://dpaste.dzfl.pl/36674a13


module testcase;

import std.stdio, std.typetuple;

enum ok = [TypeTuple!("one", "two", "three")];
enum er = TypeTuple!("one", "two", "three");

pragma( msg, "one", "two", "three" );
    // onetwothree
pragma( msg, ok );
    // ["one", "two", "three"]
pragma( msg, TypeTuple!("one", "two", "three") );
    // tuple("one", "two", "three")
pragma( msg, er );
    // with the pragma above commented out, the program works fine,
    // including the enum er.
    // with the pragma active, compilation fails. error message appears
    // at point of pragma processing, with the line number of the
    // enum er definition though:
    // Error: variable _er_field_0,1,2 cannot be read at compile time

void main(){
    writeln( "one", "two", "three" );
        // onetwothree
    writeln( ok );
        // ["one", "two", "three"]
    writeln( er );
        // onetwothree
}
