I think it's ambiguous whether to pronounce then abbreviate or abbreviate then pronounce. Here are some example from the Haskell world:
`seq`, `Eq`, `prev` I pronounce like the beginnings of the underlying words, so I'd say pronounce-then-abbreviate and abbreviate-then-pronounce yield the same result.
I guess this implies people are saying "SECK" (`seq`) and "ECK" (`Eq`), rhyming `prev` with "rev", and pronouncing `id` like Freud's id? (Eek.)
In fairness, I'll confess I pronounce `enum` "E-NUM", not "E-NOOM".
Do you pronounce it as "eyed", or as two letters, I-D?
