--- Comment #1 from Maksim Orlovich <maksim kde org>  2008-08-30 22:38:27 ---
Confirm regression in KJS4.1, for global scope (and other symbolics) ---
[[Put]] simply fails since ReadOnly is set. We need special codegen on
execution for ReadOnly things, and it is quite a bit of a mess since we don't
want to override readonly in general, so it needs to make sure it's bound to
the proper lexical scope. OTOH, it'll likely get more Mozilla-like semantics
doing that.

WRT to the report, though, I must point out, however, that "JavaScript 1.5" is
merely the name for the non-standard dialect supported by Mozilla, and is in no
way, shape, or form a standard, and has quite a few extensions. The relevant
standard is ECMAScript 3 (ECMA 262-3), which does not list such a construct.
The upcoming version 3.1 will include const, as well as many other vendor
extensions other implementations pretty much had to implement for compatibility
anyway.
