| I've scanned through this thread and did not find the main
reason I prefer TCL over PERL. In TCL, variable scope
requires declaration of globals. In PERL, you declare
local variables. This single fact also gives argument
about being able to represent the two languages "equally"
(discussed previously in this tread). Can a functionally
equivalent translation be done? Yes. Is the translation
identical? No.

The practice of "sensibly chosen defaults" is one of the best things
about Tcl and Tk. While there's often a lot of things you can twiddle,
usually you can leave well alone and get the right effect. While being
more portable to boot too.
Donal.
