Hi,
the following doesn't work:

bundle bc
bc.from = 2
loop i=bc.from..3
print i

I'm not sure it's supposed to work, but at least it seems to contradict this
explanation from the manual (section 12.2):
"The starting and ending values for the index can be given in numerical form,
by reference to predefined scalar variables, or as expressions that evaluate
to scalars."
Or isn't 'bc.from' an "expression" in this sense?
Yes, in principle it ought to be OK. But it's confusing the loop
parser because the dot in "bc.from" is getting mixed up with the
dots in the "from..to" formulation. The alternative,
loop i=bc["from"]..3
works alright. I'll see about fixing this.
