<masak> m​: say "foo".comb(/o/)
<camelia> rakudo-moar d9f58f​: OUTPUT«o o␤»
<masak> m​: say "foo".comb('o')
<camelia> rakudo-moar d9f58f​: OUTPUT«Cannot call 'comb' [...]»
* masak suggests the latter form work, too
<masak> reason​: I saw some code I had written where I had a regex with
just a literal string in it. I thought "hey, I ought to be able to get
away with writing just the string here..."
<masak> didn't work.
<colomon> +1
<colomon> just a string does work with subst.
<colomon> m​: say "foo".subst("o","e")
<camelia> rakudo-moar d9f58f​: OUTPUT«feo␤»
<masak> colomon​: good point.
* masak submits NYI rakudobug

Added; updated the already existing tests in S32-str/comb.t to include some more conditions.
