In the REPL, to test some code, I often do things like
julia> a = 0 0 julia> for i=1:3 a+=i end
But under Julia 1.0 this will now throw an error
ERROR: UndefVarError: a not defined Stacktrace:  top-level scope at ./REPL:2 [inlined]  top-level scope at ./none:0
The fix is to define
julia> global a=0
which is quite annoying. Is there a way to implicitly make every variable declaration in the REPL global?
