Problem
It is an easy mistake to pass a string to
.implies()
instead of a hash. We have other routines that do just take option names, like.conflicts()
.See: #1852
Solution
Assume the users intent was to set the option to true, like a simple boolean option.
An alternative would be to throw an error, but that would probably need to wait for a semver major release since it would break programs that might otherwise be functional.
(Both of these were included as possible approaches in #1852.)
ChangeLog
(Leaving out of changelog as this is a quiet fixup rather than a feature as such.)
