Minimal example:

class: Test @(
	construct => func @(x => 1, y => 2) {
		<% x :: y
	}
)
new: Test()

Causes parser to try to parse ) on line 2 as prefix token. x => 1 is peek-parsed & consumed, y => 2 is skipped for some reason.
I think it has something to do with nested peek-parsing when trying to parse key-value pairs via the MapParser.

The following snippet leads to a runtime error:

sum = func: list -> $(res = 0, list.for_each(@: x -> res += x))[0]
f = @: () -> range(10).map(@: yt -> (yt - 1).pow(2)).sum()
<% f() /* Runtime error due to range(10) value not being a Unit */

Snippet above won't throw anything with .sum() removed from the second line.

Problem seems to be in dot-operator evaluator in lang/core/LibUnit.cpp
