<lang perl6>sub extension ( Str $filename --> Str ) {▼
The built-in <code>.IO.extension</code> method can be used, but it...
* doesn't include the dot in the output
* doesn't restrict extensions to letters and numbers.
Here's a custom implementation which does satisfy those requirements:
$filename.match(/:i ['.' <+alpha-[_]>+]? $ /).Str
}</lang>
Testing:
<lang perl6>say "$_ -> {(extension $_).perl}" for
'mywebsite.com/picture/image.png',
'http://mywebsite.com/picture/image.png',
