That's by design. Declaring a variable of a given name more
than once is a scripting error (always has been). You can
redefine a variable OK, but you cannot re-declare it;
re-declaration probably means the writer has forgotten about a
variable. But the "clear" command is there if you need it, to
give yourself a tabula rasa.
Wait a second, I have run my scripts repeatedly all the time, with all
the matrix and series declarations in them, without clearing out stuff
all the time explicitly.
Oh, or I guess there's a difference between pure *declaration* and
*assignment*? That would make sense, because only for bundles it's
necessary to do a pure declaration, so that would be new for me.
Still, 'clear' is a bit too heavy as it also throws away the data... Hm.
