the following will not compiler (0.50)

import windows;

int main( char[][] args )
{
 /* fine */
 int x = WS_VISIBLE & ~(WS_MAXIMIZEBOX | WS_MINIMIZEBOX | WS_SYSMENU);
 /* error */
 int u = (WS_VISIBLE) & ~(WS_MAXIMIZEBOX | WS_MINIMIZEBOX | WS_SYSMENU);
 return 0;
}

gives the error
libtest.d(9): 'TOK8065536 | 131072 | 524288' is not an lvalue

I assume this is due to the parser thinking (WS_VISIBLE) is a cast

I vote for the removal of c style casts;

Mike.

Yeah, they should go.

I'm sorry. I've found already out about the cast keyword. It's a good 
decision.
I expected to find it in the 'types' section of the manual. But it's ok 
in 'expressions' too.

Sorry again.

Once the spec is final, I expect to go through it and add a bunch of hyperlinks.
 Sorry again.

No prob. The spec is a work in progress, and I'm responsible for errors, inconsistencies, and obfuscations in it.
