I think you’ve hit the nail on the head: execution speed is apparently
a sore spot in the Ruby community, one that results in undue
defensiveness and shooting the messenger! From my reading, Perl and
Python are the primary competitors to Ruby among programming languages
at this time. I prefer the elegance of Ruby, and want it to be chosen
over the others when potential users are making such a decision.
Whereas Python cannot change its indentation requirement (and remain
Python) and Perl (version 5) cannot change its messiness, I believe Ruby
is capable of reaching a comparable level of execution speed. Solving a
problem is usually better accomplished by acknowledging it openly rather
than causing people to feel like they have committed heresy or stupidity
by raising it.
