oh, ok. I guess I didn't look at it that closely. Now that I am, I
don't see how that happens, since that script just calls
PDL::NiceSlice::perldlpp, which is in NiceSlice.pm, which has the
default engine set to Filter::Simple. But maybe I'm missing
something. Setting the PDL_NICESLICE_ENGINE environment variable to
Filter::Simple and Filter::Util::Call and running perldlpp.pl on
PGPLOT/Window.pm produces identical .pmc files, so I probably am
misunderstanding.
perldpp() is the original routine that makes the niceslice expansions.
The new Filter::Simple engine just uses the feature of Filter::Simple of
selecting where the source filters are applied. In this case, if you
look at Basic/SourceFilter/FilterSimple.pm, I'm applying the perldlpp
filter to code regions only, no comments (which skips POD, comments, and
strings). There are some print statements in that file that could be
commented out to show the output.
(So how does one view the Filter::Simple parsing results? I'd like to
see what it does to Window.pm that causes those syntax errors.)
You could uncomment the print mentioned above. I plan to update the
perldlpp.pl script to use the engines for processing correctly.
But if that's true, then the rest of my message probably doesn't apply
to the new engine, and those remaining 9 seconds are for the rest of
the PDL modules (and also PDL::Stats). Yes, "use PDL::NiceSlice" was
commented out in my module after running the .pm through the filter in
utils/perldlpp.pl.
I think the pre-compiling will help for reducing the background compile
time.

Chris
