Hawke,

In the compiler, all ambiguity resolution would be done at compile time--run
time cost zero.  In the interpreter, ambiguity resolution would be done once
the first time the symbol is encountered, the interpreter would replace it
with the appropriate fully-qualified symbol--cost fairly small.  The
programmer could also be given the option of specifing an absolute symbol
name: all symbols would be included in the global namespace (named
"global"), some of them would be nested in another namespace.  Thus

global.foo.yuck

would mean "use yuck from the foo namespace in the global namespace; if it
doesn't exist there, give an error, don't search elsewhere while

foo.yuck

would use the search algorithm.  So the small cost could be reduced to zero
in critcal cases.

would search as alredy suggested.
