[vile] Clearing errors?

[Marc Simpson]

If I trigger an error with `:oops',

store-procedure oops
  &error "oops"
~endm

how do I subsequently clear the error condition? (I'm failing to find
the relevant docs.)

The issue with the above is that once `oops' is triggered, I'm unable
to write my buffers to disk,

  [write-hook returned FALSE]

which is, um, somewhat problematic....
