9 | Even if you have a C<sub q{}>, calling C<q()> will be parsed as the | |
10 | C<q()> operator. Calling C<&q()> or C<main::q()> gets you the function. | |
11 | This test verifies this behavior for nine different operators. | |

98 | <kane-xs> bug or feature? | |
99 | <purl> You decide!!!! | |
100 | <kane-xs> [kane@coke ~]$ perlc -le'sub y{1};y(1)' | |
101 | <kane-xs> Transliteration replacement not terminated at -e line 1. | |
102 | <Nicholas> bug I think | |
103 | <kane-xs> i'll perlbug | |
104 | <rgs> feature | |
105 | <kane-xs> smiles at rgs | |
106 | <kane-xs> done | |
107 | <rgs> will be closed at not a bug, | |
108 | <rgs> like the previous reports of this one | |
109 | <Nicholas> feature being first class and second class keywords? | |
110 | <rgs> you have similar ones with q, qq, qr, qx, tr, s and m | |
111 | <rgs> one could say 1st class keywords, yes | |
112 | <rgs> and I forgot qw | |
113 | <kane-xs> hmm silly... | |
114 | <Nicholas> it's acutally operators, isn't it? | |
115 | <Nicholas> as in you can't call a subroutine with the same name as an | |
116 | operator unless you have the & ? | |
117 | <kane-xs> or fqpn (fully qualified package name) | |
118 | <kane-xs> main::y() works just fine | |
119 | <kane-xs> as does &y; but not y() | |
120 | <Andy> If that's a feature, then let's write a test that it continues | |
121 | to work like that. | |
