Name mangling

Suppose we have set the mangling configuration parameters as:

begin act
string mangle_chars ".:()<>[],{}""
string mangle_letter "_"
end

The mangle_chars string defines the following map:

• . maps to 0
• : maps to 1
• ( maps to 2
• etc.

The first ten characters map to 0 to 9, and the following characters use a through z permitting up to 36 characters to be mangled.
