[Pharo-users] Interleaving strings

I have two strings, which are typically of different lengths, and I want to interleave them, i.e.: 'abcdefg' interleaveWith: '123' Would produce 'a1b2c3defg' I know how to write this procedurally, but I have been very impressed by what Sven shows in his Medium articles, so I wondered if there is any existing mechanism that would allow me to solve this elegantly? with:collection: almost does it, but the collections have to be the same size.
