Right - this is exactly the same reason I had troubles
with a function called "limits" in solarsoft that conflicted
with similarly named variables.

When I teach a student to use IDL the first thing I tell
them is to chose 2 or 3 letter initials to represent themselves
and write *all* their programs using the naming convention
xyz_****.pro

I think it's time for ITTVIS to follow this rule by reserving
a few initial letter clusters, and use that for any future new
function, or finally bite the bullet and enforce array indexing
with square brackets - either way we can't have any more name space
pollution.

Ciao,
Paolo
