Add the ability to use lambas as functions returning a result

[lv37]

Describe the feature

It should be possible to use a lambda as a function returning a result

module main

fn main() {
	take_lambda(|| println('abc'))
}

fn take_lambda(l fn () !) {
	l() or { panic(err) }
}

Use Case

Makes it easier to create functions that return results
