Recursive Interpolation

Greetings, I've seen a few posts from the middle of last year discussing the problem of recursive interpolation: http://marc.theaimsgroup.com/?l=php-general&m=105543152906744&w=2 http://marc.theaimsgroup.com/?l=php-general&m=105542523331255&w=2 It seems there's a HEREDOC method of hacking through this problem. In the meantime, is there any other way? Here's a description of a problem I'm having and how it would be nice to see it solved: Database *FIELD* with text data in it. The text data contains sentences interspersed with $foo['bar'] array variables. The idea is that when one selects this field, PHP will interpolate $foo['bar'] with the currently defined $foo array variable. This allows for "form letter" like dispatches to be created. Given a variable $text that contains data retrieved with array variables, It'd be useful to see something: $text_i = interpolate($text) which recursively interpolates based on variables in the current namespace. Granted, this opens up a *WHOLE* mountain of problems (circular references anyone?). Is there any traction on an idea like this? Any other solutions that aren't so hackish as HEREDOCs?
