Well, the answer is yes. However, I got around this problem by renaming
local
variables in such a way that they would not comflict. For example, in
ex.ex:

include file1.e

... in file1.e
atom a
a = 1
? a
...

include file2.e

... in file2.e
atom a
a = 2
? a
...

? a

my parser would rewrite it as something like this:

atom a_1
a_1 = 1
? a
atom a_2
a_2 = 2
? a_2
? a_3

It would show the first 2 variables corectly, and Eu would crash on the
third
? statement, since it is undeclared both ways. With/without is more
tricky,
I based my parser on David Cuny's contcat program (renamed fix I
believe) which
simply commented them out.
