# Warn if ‘#<undef>’ is used in the test expression of branch.  In boolean
# context, ‘#<undef>’ counts true.  It is also often the case that a procedure
# returns ‘#<undef>’ when the return value doesn’t matter, and you shouldn’t
# rely on the value that is supposed not to matter–the procedure may change the
# return value in future (which should be ok, since the value shouldn’t have
# mattered), which can cause unintentional and hard-to-track bugs.  *Note
# Undefined values::, for the details.  We strongly recommend users to turn on
# this warning.  In future, we plan to make this default.
