Must be a way: escaping filter patterns

[Bernard Devlin]

I think this does what you require:

put "tr[1]" & cr after tList
put "tr(2)" & cr after tList
put "tr[3]" & cr after tList
put "tr[a]" & cr after tList
put "td[1]" & cr after tList
put "tra[1]" & cr after tList
filter tList without "[t][r]?[0-9]]"
put tList

Try playing around with the 2nd letter of the filter expression, and
using with/without.  It seems to work for me.  Unless I really don't
understand the problem :-)
