=head1 DESCRIPTION |
66
|
|
|
|
|
|
|
|
67
|
|
|
|
|
|
|
This module will install the L syntax extension |
68
|
|
|
|
|
|
|
into the requesting namespace. |
69
|
|
|
|
|
|
|
|
70
|
|
|
|
|
|
|
You can import the keyword multiple times under different names with different |
71
|
|
|
|
|
|
|
options: |
72
|
|
|
|
|
|
|
|
73
|
|
|
|
|
|
|
use syntax |
74
|
|
|
|
|
|
|
'method', |
75
|
|
|
|
|
|
|
'method' => { |
76
|
|
|
|
|
|
|
-as => 'classmethod', |
77
|
|
|
|
|
|
|
-invocant => '$class', |
78
|
|
|
|
|
|
|

use syntax method => { -as => 'provide' }; |
85
|
|
|
|
|
|
|
|
86
|
|
|
|
|
|
|
provide addition ($n, $m) { $n + $m } |
87
|
|
|
|
|
|
|
|
88
|
|
|
|
|
|
|
The C<-as> keyword allows you to install the keyword under a different name. |
89
|
|
|
|
|
|
|
This is especially useful if you want a separate keyword for class methods with |
90
|
|
|
|
|
|
|
a different L. |

94
|

|
|
|
|
use syntax method => { -invocant => '$me' }; |
95
|
|
|
|
|
|
|
|
96
|
|
|
|
|
|
|
method sum { $me->foo + $me->bar } |
97
|
|
|
|
|
|
|
|
98
|
|
|
|
|
|
|
Allows you to set a different default invocant. Useful if you want to import |
99
|
|
|
|
|
|
|
a second keyword for class methods that has a C<$class> invocant. |
