filter-first Function

Recommended Posts

The function filter-first lets us select the first N items from a list (sublists too). The current behaviour is to raise an error when N is greater than the length of the list. For example, it is an error to say:

(filter-first 4 '(a b c))


This definitely acceptable behaviour, but I am wondering if it is OK to ask for more than what the list has, in which case it will return only what it can (i.e., based on length of list). In other words, if I say:

(filter-first 4 '(a b c))

it will return (a b c) without error.


What do you feel? This applies to filter-last also.
