Ernest,
I've been using JessDE recently and found myself spending a considerable
amount of time checking to make sure my variables were bound and used in
the right places in the patterns. It seems to me that having a simple
way to verify/highlight the bindings visually would help in this regard.
One possibility would be to add a meta-key that would toggle the font
color of each variable and bolding the location where they are first
bound - similar to paren highlighting. This could also be done to track
variable binding/usage on the RHS as well.
Alternatively, the meta-key could cycle through each variable, a
different variable each time you press it, to change the font color of
it's binding+bold and usages in a fixed color.
Thoughts, comments?
