The interpretation semantics of { are undefined. The use of { for
comments was introduced by Forth Inc after the locals { as far as
I know. Their usage is always during interpretation. As far as
language lawyers are concerned, their is no conflict!

Existing practice in VFX Forth, Win32Forth, gForth and others 
over many years is convincing.

Everything after '--' is discarded and ignored. It's defined
so that formal comments can be used. I'll update the text.
