Modified: docs/Perl6/Spec/S32-setting-library/Str.pod Log: [S32/Str] Added Int variants to index/rindex/substr There has to be a way to send in an Int to these Str methods. Arguably, StrPos and StrLen are not Ints -- that's their point. Also, removed optionality from the $end param in substr, because IMO that would lead to MMD ties when no third argument is provided.
