Are these 'shortcuts' parameterizable?

That goes without saying:
Gradual evolutionary changes are more likely to be lasting than violent
revolutionary ones.

Which evolution is already happening:

Fortress: https://umbilicus.wordpress.com/2009/10/16/fortress-parallel-by-default/
[unfortunately died along with its patron Sun microsystems]

Agda: http://mazzo.li/posts/AgdaSort.html
which is based on Haskell but cleans up
-> to ?
forall to ?
In addition to allowing arbitrary operators like ?

Julia: http://iaindunning.com/blog/julia-unicode.html

And of course the original APL: http://aplwiki.com/FinnAplIdiomLibrary
