Are there tools to convert PHP/Perl/Python/etc to Metal?

When I see:

function addargs ($x,$y) {$z=$x+y; return $z;}

I think (using brackets because some mail clients don't like angle brackets):

[function name="addargs"]
[arglist]
[arg name="x" type="unknown"]
[arg name="y" type="unknown"]
[/arglist]
[body]
[line]z=x+y[/line]
[return]z[/return]
[/body]
[/function]

I realize that's not perfect Metal, but you get the idea.

I know PHP/Perl etc all have a "lexical/tokenizing" step when they're
compiled-- could they be converted to Metal at that step?
