p55: add 'declarator' to listop. Fixes 'pipe my ($r, $w)'

[p5sagit/p5-mst-13.2.git] / mad / t / p55.t

# Test p55, the "Perl 5 to Perl 5" translator.

# The perl core should have MAD enabled ('sh Configure -Dmad=y ...')

# The part to convert xml to Perl 5 requires XML::Parser, but it does
# not depend on Perl internals, so you can use a stable system wide
# perl

# For the p55 on the perl test suite, it should be started from the
# $perlsource/t subdir

# Instructions:
#     sh Configure -Dmad=y
#     make && make test
#     cd t && /usr/bin/prove ../mad/t/p55.t
