A6: macro invocants

[Dave Whipp]

The effect of a macro is lexical; but "the name may be installed in 
either a package or a lexical scope". If the name is installed in a 
class, can it be invoked via a variable of that class?

Example (SQL query integrated via macro):

  my Database $db = MySqlDatabase.connect(...);
  $db.select * FROM Foo WHERE Foo.bar LIKE a%b;
Could I implement this with the select function being a macro on the 
Database base class: but invoked via the $db invocant? I am aware that 
the macro would be a compile-time operation: but it could resolve into a 
run-time mechanism that uses the invocant.

Dave.
