Or it could be, that some of you think we're supposed to spend all day
RTFM before we say or do anything, and that to fail to do so with 100%
accuracy is an unforgivable offense.  I've met that kind of programmer
plenty of times, and frankly they annoy me, especially since I *do*
actually RTFM religiously 90% of the time.  By the time I actually
post about something, I've read a *lot* of stuff, to bring a
discussion to the level that I want it.  Because I know that so many
techies are going to play the game of shooting people down because
someone said one tiny wrong "unforgivable" thing.  Sometimes I ask
myself why I bother to talk to techies about anything in public
forums, because generally they will not be convinced, but I guess I'm
not quite completely tired of it.  Anyways as I believe I said
earlier, I skimmed the webpage offered.  I was in a hurry, and it
looked like was talking about user interaction in a shell.  I wrote as
much as the person who offered the link wrote: a few pithy words.  As
to why I should be responding, you may recall that I started this
thread.  About F#, not C#.  Whether Mono C# actually has an
interpreter is a minor detour as far as I'm concerned.

"Support everything" is a strategy that some people might go for, but
I think there are several things to debate:

Between Lua and F#, leaving .NET and CLR interop completely out of it,
which language has the better semantics for scripting?  F# would seem
to let you do more, at the expense of being more obtuse to the
uninitiated.

Both F# and Lua allow one to create DSLs, which can answer some
"dumbing down" problems, such as they are.  I'm going to hazard a
guess that it would be easier to do arbitrary DSL stuff in F#.

Lua will never be a substitute for C++.  F# can definitely be a
substitute for C#, over time.  As one migrates scripted code to
compiled code, F# looks like a better strategy.  Lua semantics will
always be irritating as you try to do the same drill with C++.  That's
why Squirrel exists.
