beamtea_cmd (beamtea v0.1.2)

Pure interpretation of beamtea:cmd() values into a flat list of side-effects.

Keeping this translation pure (no message sends, no timers, no spawns) means the whole command language can be unit-tested without a terminal or a running runtime. beamtea_runtime executes the resulting effects.

Flatten a command into zero or more effects. Unknown commands raise {bad_command, Cmd} so mistakes surface loudly during development.
