attributes/methods on sigils?

[Michele Dondi]

I fear, and with good reasons, that this may be too wild a case of an 
extremization, but I wonder wether, just like for example strings are 
implemented by means of special (quote-like) operators, sigils, instead of 
being syntactical creatures could be (sort of special) operators 
themselved and thus allow attributes/methods or even adverbs...

and sometimes when I send out to a client I want to have a footnote to
explain some point of godawful convoluted legal prose (why don't I
just write it clearly in the first place??! Different topic....)
