^ Alternate GC ?
0851 [matju sympat] I think I recall that Ruby 1.8 was supposed to get a new garbage
+ 0852 [ekarttun cs.] There exists a patch which implements a non-copying generational GC

^ RCR:  Add __file__ and __line__ methods to Method and Proc classes
0872 [brent mbari.] This is a multi-part message in MIME format.
0881 [matz ruby-la] First of all, I said I would fix, but I haven't.  Sorry for this.
0882 [nahi keynaut] It seems reasonable for me at the point that

^ Bob Jenkins' hashing implementation in Ruby
0889 [batsman.geo ] Just hacked it.
+ 0892 [decoux moulo] Apparently, you have not modified string.c (rb_str_hash()) it's normal ?
| 0893 [batsman.geo ] I only changed the hash in st.c (and propagated side effects in num_bins
| 0894 [decoux moulo] Yes, I think this is the replacement of '%' by '&' which make it faster
| 0895 [batsman.geo ] You mean you have already changed string.c and now it's slower?
| 0896 [decoux moulo] one-at-a-time
| 0897 [batsman.geo ] Yes, much slower. Jenkins is obviously even worse :(
| + 0898 [nobu.nokada ] Instead, use -funroll-loops option for gcc.
| | 0899 [batsman.geo ] Duh!
| | + 0900 [nobu.nokada ] Just it has not been considered necessary yet, I guess.
| | | 0901 [batsman.geo ] If it's faster and simple enough, it's good, isn't it?
| | | 0908 [matz ruby-la] No one every tried and proved.  If somebody come up with the benchmark

^ Flex reentrant?
0959 [michal rokos] * As you may see, flex scanners have become reentrant, the c++ versions
