I often find myself writing things like this:
set x [mycommand ...]
if {$x ne ""} { ... }
I'd like to be able to do this instead:
iff {set x [mycommand ...]} { ... }

You are aware that `set` returns the new value of the variable? So you
can just do:
if {[set x [mycommand ...]] ne ""} { ... }
Schelte.
