           Summary: [CTFE] pure functions cannot compute constants using

With DMD 2.053:

string impure(){return ";";}

void main() pure{
    enum s = impure(); // fail (cannot call impure function 'impure')
    mixin(impure());   // ditto
}

Removing the pure attribute from 'main' or adding it to 'impure' makes the code
pass.
This restriction is nonsensical and should be removed.
