[ Resending announcement since I missed a cc to the list ]
Karl et. al.,
I just implemented a PDLdb.pl debugger with support
for PDL::NiceSlice syntax. You can get it from the PDL
git repo and use it by placing it in your @INC path
somewhere and by setting the PERL5DB environment
variable to 'BEGIN { require "PDLdb.pl" }'
Let me know how it works and if it seems stable enough
we could consider adding it to the distribution. Maybe
even with something clever like 'pdl -d' calling it under
the hood...
Cheers,
Chris
