Templated Function pointers

[js.mdnq]

It seems one can accomplish this using delegates assigned by 
generic functions. The delegate will end hold holding the "state" 
of the function. It sort of acts like a binder. It seems to work 
but more testing needs to be done. I'm not sure how efficient it 
is or if there is a better way but basically it seems rather 
elegant(rather than trying to create some new type to deal with 
it).
