Calling "get" anywhere in a function makes a global variable undefined. Can anyone please help explaining the following?
1) without calling "get", the global variable is fine: a=0 > > Dicta = Dict{Int,Int}() > > function testGlobal() > > println(a) > > merge!(Dicta, Dict(1=>1)) > > # a=get(Dicta, 1, 0) > > println(a) > > nothing > > end > > > julia> testGlobal() 0 0 2) calling "get" (same code as above except uncommenting the "get" statement) and the global variable becomes undefined: a=0 > > Dicta = Dict{Int,Int}() > > function testGlobal() > > println(a) > > merge!(Dicta, Dict(1=>1)) > > a=get(Dicta, 1, 0) > > println(a) > > nothing > > end > > > julia> testGlobal() ERROR: UndefVarError: a not defined in testGlobal() at /xxx/testType.jl:4 3) not calling the first println, the code works, but the global a is not set: a=0 > > Dicta = Dict{Int,Int}() > > function testGlobal() > > # println(a) > > merge!(Dicta, Dict(1=>1)) > > a=get(Dicta, 1, 0) > > println(a) > > nothing > > end > > > julia> testGlobal() 1
