well you're right, me neither like very much to touch locals() and (worse) 
globals(), but

1) this is the "php interpolation" Roy Smith asked for: 
       print "$scheme://$host:$port/$route#$fragment"
   where are defined scheme, host, port, route and fragment?
   or you think also this is "code smell"?

2) I'm in no way modifying the dict, just accessing in read only.

3) I'm restricting to locals() :D


btw I never used dict to format strings, so I learned how old this feature 
is :D
