But it's allowed. I mean, this works:
import sugar
type Event = object
proc on_click(fn: proc(e: Event): int) = discard
on_click (e) => (echo e; 0)
Run
The problem of "`on_click (e) => echo e`" is that it has `void` for return
type, while ``=>`` uses `auto` in its implementation (It transforms the
expression into something like `proc (e: auto): auto = echo e`). However,
`auto` cannot be `void` (but can be anything else), so it never compiles. This
means `sugar` needs a fix.
