a bug? relevant for > 0.4.6

[rudolfII]

Hello,

the following code behaves unexpectedly:

if 1>0
beta = 0.5
print("1. beta=",beta,"\n")

for i1=1:2
end

print("2. beta = ", beta, "\n")

end
print("3. beta = ", beta, "\n")

It produces:

beta=beta
beta = beta
beta = 0.5
WARNING: imported binding for beta overwritten in module Main

while if you comment out the for cycle, you always get the
expected beta = 0.5.

Please note that the result shown above is only seen
if the kerner runs for the first time over the code.

Also note, it's not the warning but the printing of 'beta=beta'
that bothers us.

Version 0.4.6 behaves, in contrast, as expected (we get 0.5).

Thanks for your work
Ruda

Dup of #2586 and #21989

Also related to #18933 I'd say.
