Summary

0003544: immutable strings

Description

Full_Name: Oliver Bandel
Version: 3.08.0
OS: Mac OS-X
Submission from: dialin-145-254-064-192.arcor-ip.net (145.254.64.192)

Feature Wish:

keyword "immutable" for saying OCaml that a string
is an immutable string, so changing it will be
disallowed.

As in a record it is possible to say that a value
is "mutable" (instead of immutable), so for strings
(but hopefully not only in records) it would be nice
to say "immutable" to get an immutable string.

(but if only possible (or consistent) to have such an
additional keyword in records (like "mutable" is there possible)
than having this possibility only inside of records ie better than
do not have that possibility at all.

but if one could say

let immutable x = "Hello World!"

and a

x.[0] <- 'x'

would result in an error message ("x is immutable")
than this would be very nice. :)
