I like this idea best (for now). Perhaps 'constant sub foo' or 'sub
foo:constant'? By doing it that way, it is apparent to both Perl and the

And what about a negate operator (neg)?

Just curious, would it be practical to design-in a boolean-specific

Actually, I wasn't necessarily asking for any special ops (I'm not actually
asking for anything, it's just a suggestion)
Well, I used to do some embedded systems programming using C, and many of
the compilers would make attempts to optimize logical ops like
if( byte_variable & 0xF7 ){...
into something using a processor op equivalent to the 8051C
testbit( byte_variable, bit_offset).

Is Parrot to have a strings db for error and UI strings (i18n)? If so, it

GNU does offer the gettext tools library for just such a purpose. I don't

This was discussed to some extent on this list before (see RFC

Here's the situation (as I understand it):
Parrot needs to stop emitting strings exclusively in English.
Parrot needs a standard file format for a string replacement db.
Parrot should only put strings to stderr (except when told to).
Parrot should be able to emit "error IDs" instead of strings.

But perl is not parrot, and parrot doesn't need -e (unless we expect people

This might be even more "Complex" than that - what if Complex can be

my Complex $c = 3+4i;
my Complex $d = 4i;
