I haven't put any serious effort into this. I suspect that the challenges
aren't terribly technical, but probably more drudgery than anything else.
I think the most difficult would be remapping all the symbol references
from their old values to their new values in the actual il code for each
subprogram.
You could possibly save these as sequences instead of integers when you emit
il code (knowing that you're doing a partial shroud). That would make later
stuff easier, though I doubt this would work when translated from eu.ex to
Rob's binary format for il files.
Alternatively, you'd need to 'reparse' the il code to remap the symtab
references. This would require knowing which parts were symtab indices.
You'd also need to add everything to the hash table, and update other and
sundry bookkeeping items along the way. So it wouldn't be a zero parse time,
but probably much reduced.
I still wish that we could supply il code to the binder and let it produce
an il file, though I doubt Rob's changed his mind on the matter.
