Variable instances (Re: Trace on Variable assignment)

} If this is really something which people would like lint to check and
} warn I would prefer just to use the variable-name-ending-with-index
} convention. Lint already checks for singeton variables if you ask it,
} just use the option 'warn_unused_vars'. It is, however, a bit of a
} sledgehammer. It ignores variables starting with "_", eg. _Temp.
This pokes at a pet peeve of mine.
When I reverse engineered the AbsForm I wanted to have the code serve to
document it. I wanted to match on:
I had thought that by prepending an underscore the variable was anonymous.
I quickly learned that it is not, only a single underscore is treated as
anonymous. I would prefer that any variable with a leading underscore was
treated as anonymous so that the above would work if Arg2 had a different
line number than Arg1 or the types of the arguments were different.
