"You can only use strings as keys in a struct" - good enough for me. Even 
though, say, Perl calls by default some kind of internal 'to_string' function 
when a variable is used as a hash key, I'd rather write and call the needed 
'to_string' myself.

Because, for example, I do not want to rely blindly on how, say, floating point 
number is converted into string.

I actually thought of adding a check that keys are strings in my code, and 
error out if they are not.

For example, how one should treat '1' (a number, not a string) as a key ? As an 
integer key ? As unsigned integer key ? As floating point key ? If the latter - 
as single, double or quad precision ? By the way, the precision question apples 
to integers to.

...

Jordi, you might need to reconsider your misunderstandings of my 
misunderstandings.
