Thanks for the reply, Jason. I realise +, * etc. are method names, but
as Julien just discovered, not all character sequences may be used as
method names.

There is a table in the Pickaxe book [1][2] which lists all Ruby
operators, noting which of them are defined as methods and thus can be
overridden.

I was just wondering whether there is a way, via introspection, to
fetch that list programmatically from Ruby, short of inspecting the
source code for the interpreter.

Cheers,

Luciano
