Write an alternative engine, and I'll bet someone will make a pragma to switch between them.

Actually afaiui the latter issue is the problem. We already have a framework for "swapping out" the normal regex engine via the use re 'debug'; facility. The problem is that the framework more or less expects the swapped in engine ot behave just the same as the one swapped out. IE, it must set the same globals, and behave in the same quirky way. If this problem could be cleaned up providing an alternative engine would probably be feasable.

[atcroft]: james28909: That particular questions was a bit of trick, actually (depending on the country you are in). More interesting is, if you are trying to subtract from an epoch time, for instance, you might have to consider when/if DST occurs for a location,
[atcroft]: because you may have to adjust the number of seconds you change from an epoch from 86400 (not to mention leap seconds)....
[atcroft]: james28909: Although if your program is using a database, you might be able to "pass the buck" to the database and ask it to do the date change for you....
