Comment:
The error messages is currently:
{{{
error:imcc:The opcode 'new_p_ic' (new<2>) was not found. Check the type
and number of the arguments
}}}
Here's why:
* Barewords that aren't predefined variables are assumed to be labels.
* The 'ic' op fullname arg code is used both for integer constants and
labels.
* Instruction selection occurs right as we parse the op, meaning we
cannot know that there isn't a label 'INTVAL' somewhere.
Here's how we might improve the situation:
* Make label op arguments take a prefix (eg: '&')
* Make label op arguments represented by a different code in fullnames
(eg: 'lbl')
* Require predeclaration of labels
* Parse all the way through a sub before selecting instructions
I'm open to suggestions.
