when an objectbox is created, its contents («binbuf») are $-evaluated as 
when a messagebox receives a message (but commas and semicolons are left 
untouched), and then the whole contents are sent to &pd_objectmaker as a 
message. therefore [moses 42] has receiver=&pd_objectmaker, 
selector=moses, $1=42.

The selector is the creator's name, which is usually the same as the 
class' name, but not always (because aliases are possible). The difference 
is mostly only visible in the default names of helpfiles. I often say that 
the classname is the selector, even though it's not technically true, 
because it's almost true (a damn lot more than calling it the objectname, 
anyway).
