Subject: Fragile pattern matching?!
Date: Mon, 28 Feb 2005 11:17:02 +0100 [thread overview]
Message-ID: <4222EF9E.1030106@barettadeit.com> (raw)
We have an incomprehensibile warning when compiling code that looks like
the following:
type value =
| Int of int
| Float of float
| Int32 of int32
| Int64 of int64
| Bool of bool
| String of string
let to_int value = match value with
| Int x -> x
| _ -> raise Some_exception
The compiler signals a warning for a fragile pattern matching at the "_"
character.
Why in the world should this code signal such a warning?
Alex
