Is this a bug, or is the error on my side? If I set

stringToParse = "a"

Hi!

The issue is you are eagerly calling dataParser in its body.

Check out http://package.elm-lang.org/packages/Bogdanp/elm-combine/2.2.1/Combine#rec and https://github.com/Bogdanp/elm-combine/issues/7#issuecomment-177468446 for a more in-depth explanation.
