libexperimental-perl - 0.032-1 main

The experimental pragma provides an easy and convenient way to enable or
disable experimental features.
.
Experimental features were introduced in Perl 5.18, together with a warnings
category "exmperimental". When such features are used, the respective
warnings have to be turned off additionally.
