#17 haskell_count: Unescaped left brace in regex is illegal here in regex

[Paul Johnson]

When I used sloccount 2.26 on a Haskell project I got the following errors:

[...]

The fix seems to be to replace "{code}" with "\{code\}" throughout. However I'm not using Literate Haskell so I can't say that this works properly.

Edit: that is, put a backslash before each open and close curly bracket.
