What should I call a REBOL function that does list comprehensions?
dialect, list-comprehension, naming, rebol
Solution
How about `select`?
`select [(a * b) for a in 1x100 for b in 4x10 where (all [odd? a odd? b])]`
Problem
REBOL has no built-in way to perform list comprehensions. However, REBOL has a powerful facility (known as `parse`) that can be used to create domain-specific languages (DSLs). I've used `parse` to create such a mini-DSL for list comprehensions. In order to interpret the expression, the block containing the comprehension is passed to a function, which for lack of a better term I've called `comprehend`. Example: ``` comprehend [(a * b) for a in 1x100 for b in 4x10 where (all [odd? a odd? b])] ``` For some reason, `comprehend` doesn't sound right to me, but something like `eval` is too general. I haven't found any other language that requires a keyword or function for list comprehensions. They are pure syntactic sugar wherever they exist. Unfortunately I don't have that option. So, seeing that I must have a function, what's a good, succinct, logical name for it?
