I have time to dedicate to fixing this to submit a PR but I need help to figure out what's going on. I just have wild guesses at this point as I'm not familiar with SimpleTraits and I'm barely acquainted with MacroTools. My main motivation is getting LightGraphs working.

[iamed2]

Looks like this is a MacroTools bug which is fixed on master of that package.

Thanks! Note, that if you are also concerned about deprecations: with moving to where syntax, there is a slight problem: https://github.com/mauro3/SimpleTraits.jl/issues/46 . I've been exploring some alternatives on https://github.com/mauro3/SimpleTraits.jl/tree/m3/associated-types (among other things).

(Also note, that I'm on vacation from tomorrow for a week, so I probably can't help then.)

[iamed2]

At this point I'm not too worried about deprecations as new ones could pop up at any time between now and 0.7 release. I just need packages to work so I can test that my packages work :)

I think just getting the version tagging going starting with MacroTools is all that's necessary. Once this package can set a lower bound on the next release of MacroTools then I can try to get LightGraphs to set a lower bound on this package, etc.

Until then I'll work on master everything

[mauro3]

I just updated the package to run again on 0.7 (on master for now, but I could tag if desired). However the parametric method deprecations remain, for now.
