I agree that, for the moment, the current size of REGEXP_CACHE_SIZE (== 20) is good enough. But, for instance, regular expression is heavily used for displaying such complicated script as Indic to genarate composition. Gnus also uses regexp frequently. If they are mixed (i.e. for people reading Devanagari mails in Gnus), I'm sure the size 20 is not enough. But, hmmm, perhaps 40 is enough. I have to estimate it. --- Ken'ichi HANDA handa@m17n.org
