Are dictionaries on the stack or on the heap? (programming.dev)

I can’t look at the source right now, but it’s likely heap. Swift stdlib collections typically use a buffer that is a reference type. The whole ‘copy on write’ thing requires reference types somewhere in the guts (if I remember correctly).
