Since everything is "local to a module" now, the only point in making a
distinction is to prevent unintended shadowing of global variables:

foo = x y z ;

...

rule bar ( )
{
return $(foo) ;
}

rule bar ( x )
{
local foo = $(x:G) ; # oops, unintentionally changes meaning of bar
...

return [ bar ] ;
}
