Re: [WWdevel] replacing PGcomplex.pm with Parser/Legacy/PGcomplexmacros.pl

[P. G. L. <gl...@um...>]

Hi Davide, Mike, et al.,

We've had trouble with the non-parser PGcomplexmacros.pl, and have been 
using the Parser based version for the last year or so.  We're not putting 
it under any real stress (just checking ordinary boring complex numbers), 
but it's worked well for us.  So I'm for making the change to using that 
as the default.
