Whitespace removal is not a solution for code length problems.
You might have a new problem if you do it. "|" is very similar
to the lowercase "L" and uppercase "i".

It's just an extra 3 characters (", ?" or "?, "). For most people,
this is not a problem at all. people tend to write "one statement per line"
rather than "multi statement line". I myself usually write no more than
3 statements per line if they are less than 120 characters.

The real problem is there is no consistency for "haystack vs needle"
position. There are RFCs to fix this (along with the naming convention
problem), but none of them are successful.

Not so poor if we
* use "~>" as pipe operator rather than "|>"
* redesign the api under their proper namespace and strictly place
  the "haystack" as the first function argument.

Hendra Gunawan.
