In Lecture7， code sum(Fun(f, Line())) is is not working. The error is follows:

I have to use -500 .. 500 instead

dlfivefifty commented 5 years ago

Thanks, this looks like a bug in DomainSets.jl, I'll move the issue there.

Ah, it's fixed on master https://github.com/JuliaApproximation/DomainSets.jl/issues/34

I'll get them to tag a new version.
