ruby-dev summary 25709-25740

Here is a summary of articles posted to ruby-dev ML last week.

[ruby-dev:25713] pthread trouble on sighandler

Nagai proposed a solution on signal handlers of ruby that enables
native thread, and it was tentatively applied to ruby-1.9.
That solution enables the ruby to ignore signals which are caused
by other threads.

[ruby-dev:25726] named capture

Nishiyama proposed that MatchData#[] receives a symbol and a string, and
returns matched data which is indicated by a label on a regular expression.
That proposal is for a ruby with Oniguruma as a regular expression engine,
as Oniguruma has a feature called "named capture" to specify matched strings
using labels.

Can someone please provide some sample code for this? I'm not sure I
get it.

Thanks.
