This code doesn't compile properly.  The first line in classTemplate 
works, but the second reports the error "no property 'type' for type

not sure but shouldn't it be:

class classTemplate (alias parameter)

instead? Compiles fine with this change!

     {
         int value = parameter.constant;
         parameter.type field;

If I understand it correctly, using alias only loosens restrictions on 
the types of symbols you can pass for the argument.  So that only shows 
that the bug doesn't exist for alias arguments, and that it remains for 
non-alias.
