Devel::PrettyTrace - prints stack traces with arguments expanded into readable format
use Devel::PrettyTrace; sub foo{ bar(); } sub bar{ bt; } foo(1, "b"); #and you get main::bar() called at foo.pl line 4 main::foo( [0] 1, [1] "b" ) called at foo.pl line 10

$Deeplimit
How many call frames to go up. Defaults to 0 (unlimited).
$Skiplevels
How many calls up of the current frame to start printing. Defaults to 0 (do not skip anything).
%IgnorePkg
Functions in a packages that are hash keys of %IgnorePkg are not shown in the stack trace output.
%Opts
Options for Data::Printer, that determine how to render arguments. If you need special formatting, do it here.
