In some simple cases, it can help to insert
let (+) = Int32.add
let (-) = Int32.sub
...
at the beginning of your files (or better to put these declarations
within a small module that you open only when you need the infix
notation). You can even adopt other notations, such as +!, -!,
etc. Only the first character is used to determine the operator
precedence.
Beware of the lexical issue with multiplication :-)
Hope this helps,
