Other amusing quotes of the week:
"Also [scripting languages] 'don't scale well', which I guess means that
they don't make it inconvenient to design badly."
"someday we'll need meta-software that converts from obsolete languages
into modern ones"
"Don't we call that compilers?"
[Actually that's kinda backwards, isn't it?]
"how about a language where you program with unit vectors: orientation
oriented programming"
"what you just typed isn't even well typed"
(The compiler tells me this all the time BTW...)

its from the mailing list, isn't it?

What, you think *I* could invent something this awesome?
Yes, of course it's from the mailing list...

In what way is that different from "zero or more As"?

Except that regular expressions are an obscure topic used almost nowhere
except in text-mangling languages like Perl.

Sure. Just expressed in an unecessarily cryptic mannar.
If a state machine is a good way to solve your problem, why not express
it clearly? And why limit it to only operating on characters?

That's the third time I've heard somebody say that. I've yet to see it.

It's no secret that emacs and vi think this is a good idea. I don't
recall seeing any other editors use it though.

Really. Because your list seems to include only low-level scripting
languages. I don't see regexs in Pascal, C, Eiffel, etc.

I'm pretty sure that Haskell is not the only programming language that
offers real parser construction tools. Parsec is merely an example of
such. (If you /really/ want to split hairs, Parsec has actually been
ported to [at least] Java, Ruby and C#. But that's not the point.)

Right. Because Unix text-mangling is all that happens in "the real
world", naturally...

Sorry. That *was* kind of harsh.

It is clearly expressed, and it's not limited to only operating on
characters. What can I say?

No. Most anything working with text.

Libraries, dear. Few languages have them built into the syntax.

Sure. And the other languages have real parser tools too. Bison, for
example, if nothing else.

No, because it's used much more widely, yet you've never seen it. Every
state machine is a regular expression matcher. Those pictures of state
transitions in TCP? Regular expressions. The "railroad track" diagrams in
the Pascal standard? Regular expressions.

That's not the point. Replace "A" with "phone number" and you have the same
problem.

No, they're really not. That's what I'm trying to explain. That's like
saying "state machines are really irrelevant" or "parsers are an obscure topic."

Amusingly, that's exactly true. :-)
