I have a sublanguage called "DPath" (inspired by XPath) which is used like this: 
    $data = ...# some Perl data structure
    @resultlist = dpath('/AAA/BBB/*/CCC')->match($data);

[download]
In @resultlist are all elements of $data which match the path '/AAA/BBB/*/CCC'. Due to its "matching nature" this could imho look more naturally when expressed with an overloaded '~~' (and maybe some prototype "dpath($)"), like this: 
    $data = ...# some Perl data structure
    @resultlist = $data ~~ dpath '/AAA/BBB/*/CCC';

[download]

That's what I want to do.

The dpath() function returns an object of a class to which I hoped to bind the overloading.

Thanks,
Steffen
