New folks and such

[flewellyn]

Well, apparently I have some new readers. Not sure why, since I rarely post anything of value (hence the journal title).

So, introduce yourselves and such!

Actually, it's a LISP pun, isn't it? Didn't recognize the #' convention, having been brought up on Scheme.

[flewellyn.livejournal.com]

Yes, Common Lisp, to be specific. The language has a separate namespace for functions and variables, so the #' operator (reader-macro, expands to (function ...)) helps to distinguish which namespace you're talking about, in non-obvious cases. CL's a very nifty language; not quite as abstractly beautiful as Scheme, but far more useful, IMNHBNWBHO.

So yeah, welcome!

Although whether or not a lambda form is treated as a function object or executed has to do with whether it's in a function position, so using #' isn't really necessary, and is two extra characters. I never do for lambda. :)

Right, but that's one of the obvious cases. #' is for non-obvious ones. :-)
