Comment (by raimue at macports.org):

 Not that easy to implement, I think. It would require to check full Tcl
 syntax.
 For example:
 {{{
 set cd foo   # valid
 set [cd foo] # invalid
 cd foo       # invalid
 set exit 1   # valid
 exit 1       # invalid
 do; exit 1   # invalid
 do && exit 1 # invalid
 }}}

 But this can also be complexer, as you can create variable functions:
 {{{
 set foo exit
 $foo 1       # is now equivalent to `exit 1'
 }}}
