Right, that's the point. There's nothing else that *would* make any
syntactic sense in a parameter list besides "^Type" that isn't already
allowed in them.
No, I think you *missed* the point. "^Type" defines a new type. "0..5"
defines a new type. "set of (Alpha, Beta, Gamma)" defines a new type.
"record a, b: longint end" defines a new types. All four of these can be
used either to declare a named type or for an anonymous type in a
variable declaration. However none of these can be used in a parameter
declaration. Parameter declarations and variable declarations are
different beasts, they have different rules (for example you can't
declare open arrays outside of parameter declarations and no, dynamic
arrays don't count, cause despite them sharing a syntax dynamic arrays
and open arrays are different concepts).
