Ah, sneaky.

Cool, I'll give that a try. Thanks for the tip.

Yes, but I have no idea what "World of Warcraft" or "Somatic Cell
Nuclear Replacement" has to do with the current topic. ;-)

Both. tiOPF has a debug visitor class that generates whole class
output, and for everything else, I can use the various Log() or
LogXXX() calls.  Code Templates come in handy here, and auto-wraps
such code in IFDEF's so they don't accidentally get left in the code
or compiled in release builds.

That's pretty neat.

I'll get a fpc trunk update tomorrow and retest.
