APL is not at all a symbolic language. It's more like an imperative language with fancy builtins and pretty syntax.

My searches for "graph computation" lead me to think that's just another name for an AST (a very simple one, but one nonetheless), which is what the blog is creating. An implementation could certainly make optimized code for AST subtrees, but it's a lot of complexity.
