I' had trouble seeing the benefit of adding "true" and "false" as trivial 
conditions, taking no arguments. If what was originally asked for is for 
subconditions of and/or to be expanded, yielding "true", "false", or possibly 
an entirely new condition, it makes more sense.

The way things work now is that conditions appear certain places where a 
condition is expected and nothing else, while expansion items and variables 
are signalled by a '$'. But it shouldn't be too hard to check if the first 
character is a '$' and, in that case, perform a string expansion and evaluate 
the result as a boolean instead. That won't be possible directly in an ${if}, 
though, so you can have ${if and{{${lookup mysql{SELECT 1 FROM users WHERE 
name = '$local_part'}}{$acl_m1}}}, but not simply ${if ${lookup mysql{SELECT 
enabled FROM users WHERE name = '$local_part'}} {foo}{bar}}.
