Robert Burke commented on BEAM-12158:
-------------------------------------
Fair. The work around seems reasonable though all things considered. Knowing
the cause of the issue does temper my upset. If one's running in the local
directory, there doesn't seem to be another way to avoid it, beyond fairly
unambiguous file names. This is very helpful James! Thank you.
