Can you explain the utility of both of them? I am not big into
functional programming so I am not seeing it.
The purpose of `bindTo` is to emulate the `let` expressions found in
many functional languages (see
http://en.wikipedia.org/wiki/Let_expression). The idea is to bind a
value to a name for the limited scope of a single expression.
Note that `bindTo` could be implemented as:
alias bindTo = std.functional.unaryFun;
and I'll probably change the implementation to this if this PR will be
chosen. The reason I think `bindTo` is needed even if it's just an alias
to `unaryFun` is that `bindTo` conveys better that the you are binding a
name to a value, not just overcomplicating the code.
And my impression (in lisp/clojure) was, that let emulates (named)
variables of imperative languages :P
