|
|
|
|
This module allows you to write multi-line perl statements in reverse order so that it "reads better". For example, normally one would write the code from the SYNOPSIS as: |
|
55
|
|
|
|
|
|
|
|
|
56
|
|
|
|
|
|
|
my @arr = (1..10); |
|
57
|
|
|
|
|
|
|
|
|
58
|
|
|
|
|
|
|
print # lastly, display result |
|
59
|
|
|
|
|
|
|
join ":", # and glue together |
|
60
|
|
|
|
|
|
|
map { $_**3 } # then cube each one |
|
61
|
|
|
|
|
|
|
grep { $_ % 2 } # then get the odd ones |
|
