The following example on latest Julia master produces the error below. I managed to reproduce it using Flux#master and the latest released version in a simple example, but I am not entirely sure if it has anything to do with that package, or where to report this; suggestions would be appreciated. Works fine (without error) on Julia v1.0.1.
VERSION
function foo() end
using Flux
function bar() end
Output:
julia> VERSION
v"1.1.0-DEV.515"
julia> function foo() end
foo (generic function with 1 method)
julia> using Flux
julia> function bar() end
Error showing value of type typeof(bar):
ERROR: type Task has no field parent
