^ A few questions
2224 [Andy Toolshe] A couple of questions have come up that I need some input on. These
+ 2225 [matz netlab.] Yes, it's for statically linked extensions.
+ 2227 [c.hintze gmx] A few questions
2231 [andy Toolshe] Then why does this file exist? Solely for static linking?

2243 [andy Toolshe] "yes", apparently! Thanks for clarifying it.

2239 [h.fulton att] Thanks for asking, Andy... :)
2242 [andy Toolshe] Excellent! Best of luck.
^ setter() for local variables
2241 [decoux moulo] Do it exist a way to define setter() method for local variables (like for

+ 2247 [decoux moulo] No, I don't think because this was just an example. I can store Hash or

| + 2261 [decoux moulo] if (dbst->marshal)
| + 2294 [matz netlab.] Something like this

| | + 2296 [matz netlab.] def =(k,v)
| | + 2299 [decoux moulo] I must do the same for def , in theory, i.e.
| | + 2307 [matz netlab.] Hmm, I didn't know bdb supports transaction.
| | + 2326 [decoux moulo] It can be written like this (well if I can write it :-))
| + 2358 [decoux moulo] I just need to write this, no ?
| 2366 [matz netlab.] Hmm,

2268 [h.fulton att] Greetings, fellow Ruby enthusiasts.

2298 [andy Toolshe] My Rube-Goldberg attempt used tracefunc to hook into the dispatcher,

+ 2319 [mrilu ale.cx] I can't expect it even if I somebody says there's a trick in here.
^ Function of Array.filter surprises me
2330 [mrilu ale.cx] I don't expect Array.filter to do task of Array.replace_with!.
2331 [matz netlab.] I have to admit `filter' is not a best name; some proposed `collect!',
2352 [mengx nielse] Would convert/convert! or transform/transform! be better that collect/filter?
2353 [schneik us.i] # >
2354 [quinn euro.u] filter also makes sense to anyone who's used any language other than smalltalk

2343 [decoux moulo] I can open a dbm file with $SAFE = 4, it's normal ?
2345 [matz netlab.] Yes, you can open dbm iff the path is untainted.
2344 [decoux moulo] How work rb_catch ?
+ 2346 [matz netlab.] Oops, it's a bug.

2364 [kikutani gal] Sounds good.

^ Marshal: Want string out, but want depth specified?
2375 [hgs dmu.ac.u] @encoded = [Marshal.dump(@decoded, , depth)].pack("m")
2378 [matz netlab.] Because you can't omit the second argument.
+ 2405 [quinn envy.u] So, when are we going to get keyword args in ruby? :)
| 2415 [matz netlab.] In Ruby 1.7. Development would be started in summer hopefully.
+ 2421 [hgs dmu.ac.u] I tried this because I can omit the second and third arguments together.
2422 [matz netlab.] Could you submit a problem reproducing script and precise error
2423 [hgs dmu.ac.u] Well, in the mean time I took out the explicit depth spec, so I could get
