shouldn't cast(Object)cast(void*)anything work?

[Davidl]

i don't think compiler could eliminate the following :

union __exp
{
	Expression _m_exp;
	int	   i;
}
__exp EXP_CANT_INTERPRET
static this()
{
    EXP_CANT_INTERPRET.i=1;
}

to :

simply cast(Expression)1;

while in runtime
return cast(Expression)1; would generate literal 1 and retn
and the example use union trick could possibly need to copy a var which  
holds the value of 1



and it's strange for the error message goes away when it becomes the first  
member ;)
:o because the first member's initializer is the union's default  
initializer?
