No it's not. Assembler is low-level crunching. It's unstructured, typeless,
and unportable. If you want portable asm, go to C.
This wasn't about style. It's about "cryptic". Good and bad style is
possible in any language.

Perl's syntax is quite straightforward for a human. It is, however, a
language of side-effects. This is what can make it difficult to follow.
It's also what gives it part of its power.

Funny, I don't.

There are very, very few places you _must_ use $_. Writing clean code
is no more difficult than in any other language. It's just easy in
perl to write things poorly. I put this blame on the programmer, though,
not the language.

This point totally escapes me. Dos, like C and Perl is/was successful
because of the amount of software available for it. It doesn't matter
what the software was written in.

I wouldn't call it avertising, but I think I know what you're saying. These
languages were "advertised" by other users because they worked. They did
the job better than the other choices.

In theory, theory and practice are the same. In practice, they're not.
