This seems pretty straight forward and clear to me.
Perhaps the thing that I find hardest in the tacit version is the use of "o" to
represent "@:" (requires an extra level of mental substitution). I think most
reasonably fluent J readers would find the following easier to parse/understand:
isMunchausen =: = +/@:^~@:digits
... which is more obviously a 2-verb train (hook)
However I imagine someone not familiar with J would find that more intimidating.
