in reply to Redefining Imported Subs: of scope and no

Don't mess with say, it will byte you or a later maintainer of this code.

Instead, (1) define sub debug {...}; with a plain old if inside. (2) Replace all occurences of say with debug(). (3) Replace those say's that aren't really for debugging back again. (4) Re-run your tests to see if anything got lost.

You can then consider moving debug() to a separate module for re-use, or switch to Log4perl altogether as other monk suggests here, or even write a debug_off() sub that replaces debug() on the fly. But at least it's not like "Hey, say() prints nothing! Our perl interpreter must be broken!"

[Corion]: marto: Redoing something on new infrastructure sounds fun. At least you can reuse your previous experience :)
[marto]: I'm looking forwads to it. The video sources are dying, and they don't have the hardware to play them back (old tape formats, not just VHS + Laserdisc etc)
[marto]: I'll be interested to see what difference in terms of file size/quality the new codecs make. I enjoy working on things like this, so that's a bonus
[Corion]: Ah, cool! So it's not an inhouse youtube but for a wider consumption
[marto]: last time it was IE6 clients, now they're on 11, so more scope there also, in terms of UI and playback
[marto]: in house as in Company network, not internet connected (power stations and the corporate HQs)
