Discussion

Dave Mitchell asked several questions about the slowness of two tests: ext/XS-APItest/t/handy.t and ext/XS-APItest/t/utf8.t.

Todd Rinaldo sent an email to cpan-workers regarding the toolchain and removal of . from @INC. Discussion continued.

Dave Mitchell has made the desired changes to the output format of op_dump() discussed previously.

Karl Williamson notes that perl still attempts to compile regular expressions, even if there are parsing errors, and wonders if there's a valid reason for it.
