# TODO:   1) Tol is marvelous, did you know you can actually create 2 variables
#          with identical names differing only in the grammar type?.. example..
#          Real a1 = 2;
#          Set  a1 = SetOfText("","");
#          (This will create 2 separate variables with the same name.. amazing huh?)
#          This is PERFECLTY possible in our amazing language, wich SUCKS for
#          the purpuse of this procedure... that is, because analyzed text is
#          arbitrary. With no reading rules, i can't really determine the
#          variable type before calling BalloonHlp. If two variables happen to
#          have the same name, the ::TclInfoVar loop function will catch the info
#          on the last valid grammar type in the checklist (See Editor::BalloonHlp 
#          for more details).
#          
#          The idea would be to determine the grammar type before calling BalloonHlp.
#          I ain't genious enought to take it that far out.... yet. :-D
#
#         2) I managed to exclude comment lines from being parsed as valid tags.
#            If you can manage to exclude text or quote delimited expressions
#            from the loop, you're my geek... and offcourse, you defenetly have
#            more free time than me. Good Luck.
