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. |

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