Why don't anonimous structs and unions work if written in a function scope? This
would be useful for specifying the stack frame's layout.
For example:
uint func(float a)
{
union
{
uint b;
float c;
}
c = a;
return b;
}

But yes, this should be consistent.

But to avoid the copy, perhaps the good old pointer cast might be better.

Yes you're right. I only wanted to show what I meant:
I wasn't able to think of a better example. :-)
