Lines 46-52 of t/spec/S02-literals/pairs.t claims that the colonpair notation should produce a Bool instead of an Int:
#?rakudo todo 'Adverbial pairs without should produce a Bool (not Int)' is f2(:a), "Bool", "':a' is a named"; #?rakudo todo '.() sub calls' is(f2.(:a), "Bool", "in 'f2.(:a)', ':a' is a named"); #?rakudo todo 'Adverbial pairs without should produce a Bool (not Int)' is $f2(:a), "Bool", "in '\$f2(:a)', ':a' is a named"; However, S02 says that C<:a> corresponds to C<< a => 1 >> in fatarrow notation, which seems to argue that C<:a> should in fact have an Int value. Are the tests correct here, or am I reading too much into the synopsis description? Pm
