Thanks for the report. Since the commands in the file are executed in a
different execution context, and do not interrupt the parsing of the
current command, what do you think this should do? Bash could simply
disallow that construct if it's in the middle of parsing a compound
command, as other shells do, but it's always done its best to continue
with the compound command.
