Ah, I see. I take it this means it is not possible to use sapply
with strapply directly. (I'd have to write a function that wraps
strapply with different argument names, and then sapply that.) Anyway,
I managed to do what I wanted by collapsing my multiple regexes into
one, so it's good for now. Thanks for the help.
