I'm still struggling with understanding Julia's scopes. Are they consistent? Why does the following happen? I'd expect "y" to be lexically bound by the let. This is version 0.2.
julia> let y = 4; eval(symbol("y")); end
ERROR: y not defined
In addition, one can refer to certain scopes (modules, types) with
functions such as isdefined(), but not to others (let scopes, for
instance). Why is that?
