<TimToady> while we're at it, let's make backtraces print all the arguments
to all the routines...
<TimToady> well, the short ones, anyway

That would be awesome!!!

In fact, this idea was mentioned a couple of times. One of those times it
was discussed whether .perl, .gist or something else should be used for the
output, but unfortunately I cannot find the link (perhaps somebody else
will. However, there was no final decision).

From @hoelzro

I support this idea in general, but we have to be careful if we want Perl 6 to be used in systems that support things like PCI compliance. You don't want the arguments to process-credit-card(Str $cc-num, Str $first-name, Str $last-name) to appear in logs!

We'll likely only be able to support this if some kind of "debug mode" that disables optimizations is switched on. We already discard some of the info needed to do this, and we'll be getting rather more aggressive at optimization in the coming months. And performance is more pressing than this nice-to-have.

From @AlexDaniel

FWIW I agree about the “debug” mode.
That said, it isn't just a nice-to-have. This is something that can make people mention Perl 6 when discussing the most amazing features of modern programming languages… much like people mention grammars today :)
