[kriskowal]

Progresses: #2125

@turadg This is a wholesale upgrade to ava@^6 in endo and it looks great except there appears to be a bad interaction between ses, execa, and the new ava. I’m investigating this now.

Root cause of this is in mimic-fn, retained by onetime, retained by execava, which does a hasty toString patch which does not compose well with our “enablements” on toString (replacing the value with a get descriptor). I’ve pushed a patch and seek to get it upstream. sindresorhus/mimic-function#51

LGTM.

LGTM. Leaving to your discretion when to drop the patch (since your sindresorhus/mimic-function#51 is released in https://www.npmjs.com/package/mimic-function/v/5.0.1 )

Wow, we’ve never gotten one of these upstreamed overnight.
