Here is a bug which showed up in colomon++'s ABC module during
precompilation.
One needs three module files to reproduce this:
# file ./lib/A/Role.pm
use v6;
role A::Role { }
# file ./lib/A/Class1.pm
use v6;
use A::Role;
class A::Class1 does A::Role { }
# file ./lib/A/Class2.pm
use v6;
use A::Role;
use A::Class1;
class A::Classs2 does A::Role { }
running 'ufo && make' to precompile those modules produces this error:
mkdir -p `dirname 'blib/lib/A/Role.pir'`
env
PERL6LIB=/home/moritz/tmp/oddness/blib/lib:/home/moritz/tmp/oddness/lib:
perl6 --target=pir --output=blib/lib/A/Role.pir lib/A/Role.pm
mkdir -p `dirname 'blib/lib/A/Class1.pir'`
env
PERL6LIB=/home/moritz/tmp/oddness/blib/lib:/home/moritz/tmp/oddness/lib:
perl6 --target=pir --output=blib/lib/A/Class1.pir lib/A/Class1.pm
mkdir -p `dirname 'blib/lib/A/Class2.pir'`
env
PERL6LIB=/home/moritz/tmp/oddness/blib/lib:/home/moritz/tmp/oddness/lib:
perl6 --target=pir --output=blib/lib/A/Class2.pir lib/A/Class2.pm
===SORRY!===
None of the parametric role variants for 'A::Role' matched the arguments
supplied.
Cannot call ''; none of these signatures match:
make: *** [blib/lib/A/Class2.pir] Error 1
The fact that the list of candidates is empty indicates that it is lost
somewhere during the precompilation.
