You pass 'a' trough 'g()' into 'f()'. f() modifies this table by
removing all it's entries, effectively modifying 'a'. g() modifies the
'set' variable, but this does not mean it also changes 'a' in the global
scope, it merely changes the local varable 'set', which happens to point
to the same table as 'a'.
