I agree. In another post, you wrote about several other built-in
functions in APL, and how useful they had been.

A long time ago, I tried to use built-in sequence operations in Euphoria
whenever possible, because at that time I had assumed that they are
aöways faster than loops. In most cases I ended up with 'for' or 'while'
loops instead, just because what I wanted to do was not possible with
built-in sequence operations.

So if built-in sequence operations should really become an important
feature of Euphoria (like it had been in APL), Euphoria actually should
provide more support for it (like there had been in APL).
Besides a filter() routine, functions such as sum(s), min(s), max(s)
spontaneously come to my mind.
