the second, or mycd.area(a,b)=a*b

The original model split that between CDs and the object syntax it is true.

There is of course nothing to stop you having a CD that allows the
definition of symbols within the language.

For example the programming cd


has constructs for "let" and "function definition" which give
local interpretation to OMV  which may then be used
to reference those functions by name.
