Isn't `each` too much of a good thing?

No. Generally speaking they happen (or at least are tried) once 
per binary expression (that includes assignments).

In "a = b(c + d);" you have 3:
1. return type of `b(c+d)` to `a` type
2. `c` to `d` type (or the opposite)
3. `c + d` to the type of `c` first param.

But those are essential. It's not a question of too much / 
efficiency.
A backend cant do its job without them and a frontend that 
doesn't do them automatically means that the language is a joke.
