    alias T TypeTuple;

{
    enum foobar = 2;
}

void main()
{
    foreach(sym; TypeTuple!(int, double)) // OK
        pragma(msg, sym.stringof);

    foreach(sym; TypeTuple!(foobar))      // OK
        pragma(msg, sym.stringof);

    foreach(sym; TypeTuple!(main))        // OK
        pragma(msg, sym.stringof);

    foreach(sym; TypeTuple!(int, foobar)) // Error: type int has no value
        pragma(msg, sym.stringof);

    foreach(sym; TypeTuple!(int, main))   // Error: type int has no value
        pragma(msg, sym.stringof);
}


----

As soon as a symbol is part of the tuple it is treated as expression tuple. Foreach with an expression tuple then tries to use each tuple element as initializer which fails for types.
