Hey! At first look it does look like something bolts-y so I'm 
very open to discussing the usecases/problems to figure it out. 
And it initially looks like very cool stuff!

Am I correct in assuming that FunctionEditor is a way to 
"stringify" various attributes of a function, in order to create 
string versions of new functions, in order to mixin new functions?

Where being able to mock interfaces is one usecase?

What other usecases would there be?

I looked at the real usage you have, but I don't think I 
understood the dispatcher and discriminator

And, one last question:

If string interpolation was around would the interface you've 
designed be the same?

I opened an issue in github as well: 
https://github.com/aliak00/bolts/issues/9 just incase it makes 
more sense to discuss it there.

Cheers!
