#Splitting on one or more occurrences

Say you have a string "abbcdbbfghbdbb" and you want to split it on b

"abbcdbbfghbdbb"'b/

This leaves on stack:

["a" "" "cd" "" "fgh" "d" "" ""]

Notice the empty strings ? Those are there because two b were together and nothing was in between them. At times, you want to avoid this. You can do this by

"abbcdbbfghbdbb"'b/La-

or filtering out empty strings

"abbcdbbfghbdbb"'b/{},

but that is 3 extra bytes.

A little less known operator for this particular use case is %. Apart from doing mod and map and splitting based on number ("abcd"2% = "ac"), % can also split on strings/arrays. So for the above use case:

"abbcdbbfghbdbb"'b%

will leave

["a" "cd" "fgh" "d"]

on stack.
