You're the one that suggested it, but I'll bite: you might want to embed say ruby in BEAM if you wanted to take advantage of hashicorp terraform. Perhaps you want to support middleware or a query system in another language but have the bulk of your architecture be BEAM. You might want to deduplicate internal libraries shared between teams. You might want to use a 3rd party library written in one of these langs. You might want to transition between lang X and a beam lang and what you need is to leakily expose BEAM modules using shim code as an intermediate. You might just be crazy and want to do weird shit for fun.
