feature/fset
In CL, (fset (some-access-expr) new-value)
is a macro that can be supported by every data structure that add some generic function.
The idea is good:
- similar to a reduced version of lenses
- clear code because the access pattern is used also for writing elements
The semantic is not correctly type-check proof, because it is an abuse of notation, but it is completely clear for the human mind, because it is a fixed workflow: access this element and overwrite it.
In Dok, I can support something like some-access-expr :
new-value=.
