( #3333=superdoc: print w/replies, xml ) Need Help??

The "should we, shouldn't we" debate seems to be yet another sterile academic debate from my perspective, but maybe I'm missing something. Whilst I remember making a few rods for my own back with the C macro facility, mostly related to writing macros that had side-effects, I have also seen them put to very good use.

Does anyone with a strong opinion against adding macro facilities care to give a few reasons?

On the other hand, I'd also like to see a few examples of what people would use a macro facility for in Perl. Assuming that p5 had a C-like

#define name(arg[,arg]) {\ some code here\ }

I think that's roughly the syntax

What would you use it for?

    [Corion]: Meh. I have a very simple mechanism to scrape+track prices, and even to send me mail if something changes (via cron), but SQLite doesn't support window functions, so my simple SQL to determine a price change won't work :-( Maybe I should store the DB ...
    [Corion]: ... in Pg, but that would mean that I'd have to deal with credentials and stuff :)
    [Corion]: In fact, the whole thing is just four simple programs, one App::scrape, another being DBIx::RunSQL, and one some glue to convert a JSON object into an SQL INSERT statement (+DBI connect/execute), so it would be an incredibly simple solution...
    [Corion]: ... but that simplicity falls down due to SQLite letting me down and me being too lazy to move to a real DB. Maybe DBD::CSV can handle window functions...
    [hippo]: Pg has the "trust" mechanism if you don't fancy using credentials for a trivial db.
    [Corion]: hippo: Oooh, that sounds quite nice - let me read the documentation on that :)
