Guys, i really wonder, how it differs from using a usual smalltalk syntax for
class declaration?
pragmas: '<pragma1> <pragma2>'
can be written as:
pragmas: 'pragma1 pragma2'
without any loss of extensibility/flexibility/whatever.
Of course, we can put any sequence of characters into the string
literal and parse
them in any way we want to, to extract some extra information. But is
it worth it?
But i wonder, why we should invent so over-complicated ways to do simple things?
In any way, if we need that class should carry additional information,
which needs to be formally represented in
declaration, then i why not just keep using ordinary syntax, by adding
either additional keywords, or even statements.
Just look at ProtoObject declaration:
ProtoObject subclass: #ProtoObject
instanceVariableNames: ''
classVariableNames: ''
poolDictionaries: ''
category: 'Kernel-Objects'.
ProtoObject superclass: nil
if we want to extend this, it is logically to follow the same pattern
and add any other statements, like:
MyClass foo: bar.
Just my 2c.
