Hi,
Assuming this is allowed, what will the .() calls below return?
Does the result depend on the calling context?
use junctions; # still required?
my @subs = ( sub { return 1 } ,
sub { return 2 } );
# call the closures in the junction
any(@subs).();
all(@subs).();
one(@subs).();
none(@subs).();
one(any(@subs),sub { ... }).();
I'd guess the rule is "call 'em all and return a similarly
structured junction". How far off the mark am I?
