No speed boost with opcode caches, which will be bundled in PHP 6 :)

Hello Sara, but if we were moving from flex to re2c for that tokenizing scripts we'd get a nice speed boost, too. Typically re2c based scanners are 2 to 3 times faster than lex based ones. And oh-re2c allows unicode scanning (2 byte input) and you can use the same .re to generate two .c files if necessary. best regards matcus Thursday, March 9, 2006, 6:44:45 PM, you wrote:I've heard second hand that lemon does.

Yes, I know this is more of a problem with bison and flex than with the design of ZE, but that doesn't make it any less bothersome.Do other compiler tools allow this?
