The second pattern of
StringInclude#redundant_regex?((send (regexp (str $#literal?) (regopt)) {:match :match?} $str)) is pretty useless, because it only detects cases like'str'.match?(/str/), so literal regex is matched against literal string. But does anyone write such code?That pattern was implemented that way, because, to avoid cases when the receiver is a symbol and symbol does not implement
#include?. But, it already marks as offense and autocorrectscan_be_a_symbol.match?(/abc/)! So I think this PR changes are fair.
