Subject: Strange observation on polymorphic '<'
Date: Tue, 30 Nov 2004 15:30:04 -0500 [thread overview]
Message-ID: <9E571848-430E-11D9-AF66-000A95CDFBE4@cs.unc.edu> (raw)
Hi,
I saw this on the site http://merjis.com/developers/ocaml_tutorial/ch11
The author says that even if the types of a function (let max a b = if
a>b then a else b)which internally uses the '>' operator are known (by
type inference) and are found to be ints, the ocamlopt compiler still
calls the generic 'greaterthan' function written in C to compare them.
This seems rather an over kill when a simple comparison instruction
could have done the job. Am I missing something here? Let us assume
that the function which internally uses the '<' operator is used only
in the context of integers inside the program.
