So how do you chain your implementations of hgrep and hmap?

hgrep {...} hmap {...} %h

???

Your trying to convince me that breaking the established interface is OK because there "is no use case".

(or to be precise that I have to show a use case while you don't try to prove that there is none)

I'm saying it's safer to respect symmetry because nobody can anticipate all use cases, not even you.

I don't say your code doesn't make sense from a performance analysis, BUT then

  1. it should be named in a way making evident that it can't be mixed with map, grep and sort
  2. corresponding versions of map, grep and sort should be available

A good design avoids traps and misunderstandings w/o overloading the language with edge cases!

Cheers Rolf

UPDATE:

Since I thought that uneven lists should be disallowed anyway, I think it's not too dirty to consider a single argument to be a hashref.

Like this both  hgrep \%h and hgrep %h would work and could be chained.
