PAST::Var nodes have a required attribute :scope, which can take one of the
following values:
lexical
parameter
package
keyed
I propose to add a scope "attribute". The PAST::Var node should have one
child node, which evaluates to the object of the attribute.
an example, with a global object called foo, and an attribute called bar.
Typical HLL syntax is: foo.bar
my $obj := PAST::Var.new( :name("foo"), :scope("package"), :node($/) );
PAST::Var( $obj, :name("bar"), :scope("attribute"), :node($/) );
translates to:
$P10 = get_global "foo"
$P11 = getattribute $P10, "bar
Would this be useful for other HLLs? (I'm currently thinking of Ruby, where
instance variables (object attributes) are lexically different from other
identifiers.)
