stack overflow in the code generator

[ks32849]

filter(criteria, ls) =>
*, [] : []
*, [x:xs] | criteria.@call(x) : [x] + filter(criteria,xs)
| else : filter(criteria, xs)

main ->
print(filter(divBy2, [1..20]))
where
divBy2: @(n) -> {(n % 2) == 0}

This causes an infinite loop and eventually a stack overflow in the code generator:

etc.

Where as:

main ->
print(filter( @(n) -> {(n % 2) == 0} , [1..20]))
works great. So does:

main ->
print(filter(divBy2, [1..20]))
where
divBy2(n) ->
(n % 2) == 0

Looking at this, sorry about the delay.
