Pondering Advent of Code after having done three-and-a-half1 days' worth of exercises:

I really miss Erlang. F# is nice and all, but feels like Erlang set a bar for functional thinking.

Erlang, by many measures, is not a perfectly functional language, but I nonetheless tend to write my F# code as I would do in Erlang and it doesn't feel idiomatic.

Perhaps it's just impostor syndrome.

1 I haven't gotten day 3 right yet. It's in progress and requires a full night's worth of sleep, which I haven't gotten the past few days. :)
