I started to get a strange error while debugging my code, here's a
simplified example:
julia> function foo(a)
println("foo..")
end
foo (generic function with 1 method)
julia> a = foo(2)
foo..
julia> a,b = foo(2)
foo..
ERROR: `start` has no method matching start(::Nothing)
So, the problem was a missing return value, it is strange that missing one
value did not give error but two values.... It took a quite long time to
track this down. Perhaps a bit more informative error message would be
possible...?
Cheers,
