Does colonpair notation produce a Bool or Int?

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?
