I think it's not so much namespaces but the fact that the syntax allows
you (and the compiler) to easily differentiate variables (entities in
Eiffel parlance) from types.
Some examples..
1) Variable declarations:
variable : TYPE
The identifier to the left of the colon is recognised as a variable
and the one on the right as a type.
2) Variable instantiations:
!TYPE!variable
The identifier framed by exclamation marks is recognised as a type
and the one following as a variable.
3) Selective export:
feature {TYPE}
Any identifier enclosed in curly brackets is a type.
4) Constrained generic parameters:
class GENERIC_TYPE [G -> TYPE]
All constrained generic parameters are types.
etc.
Don.
