Issue #12050 has been updated by Nobuyoshi Nakada.


Intentional, and resolved in the defined order when it is ambiguous.
I don't want to write `--enable=frozen-string-literal`, but `--enable=frozen` or shorter.

----------------------------------------
Bug #12050: Should feature processing really accept any substring of the feature name?

----------------------------------------
ruby --disable-gems -e 1
ruby --disable-gem -e 1
ruby --disable-ge -e 1
ruby --disable-g -e 1

I found this because in test_syntax.rb someone used --disable-gem and JRuby is currently doing matches on the full feature name and erroring otherwise.  If this is intentional it means no two features should ever start with the same letter...
