I thought I'd be getting along alright with F# since I'm decent at Haskell, but I feel like I'm being stumped by dead simple issues. I have some parsing code for a simple JSON parser, like this:
let rec parseObject tokens = function
| '"' :: cs -> parseString tokens cs
| ':' :: cs -> parseValue tokens cs
| '}' :: cs -> tokens, cs
...
let rec parseValue tokens = function
| c :: cs when Char.IsWhiteSpace(c) -> parseValue tokens cs
| '{' :: cs -> parseObject tokens cs
...
That won't work, because parseObject doesn't know about parseValue. Can't reverse them either or I'd get the opposite problem. So what am I supposed to do here?
