"Could be stricter", perhaps.
Do we care deeply? I doubt it, and for a good reason. The fuzzy
parsing is primarily [*1*] for humans getting interactive results
who are expected to be able to notice when the fuzziness went far
As long as we have ways for scripts and humans to feed its input in
a more strict and unambiguous way [*2*], it does not hurt anybody if
the fuzzy parser ignored crufts that it does not understand.
*1* ... and of course some coding fun and easter egg values. Think
of it as our own Eliza or Zork parser ;-).
*2* And of course we do.
