In connection with completing David Fetter's array of composites patch, 
I am looking at doing some better name mangling for array types as 
recently discussed. What I'm thinking of is prepending one or more 
underscores to the type name up to some limit (NAMEDATALEN / 2 ?) and if 
necessary truncating the result, and then looking to see if there is a 
name clash. That would, I hope, enable us to get rid of all the places 
where we require names to be no more than NAMEDATALEN - 2 chars. Does 
that seem like a reasonable approach? Will it break anything, i.e., is 
there somewhere that has assumes the array type for foo will be called 
_foo  rather than ___foo ?

cheers

andrew
