Introspection runs into endless exception reporting

[haraldsteinlechner]

in, pro3d, not all packages are up to date and i missed quite some development there, introspection runs into an endless exception reporting loop. Is this something somebody stumbled across already? it looks like this:

this might go forever... (could not wait for infinity yet to know ;))

[haraldsteinlechner]

nope, not goes forever but for several minutes. it seems to happen within custom pickler registration.

pro3d-space/PRo3D#228

PRo3D, autodeploy branch can be used to reproduce the problem.

EDIT: also i just found out that for this specific run i got complete crash within aardvark.init (which should not happen at all)

[haraldsteinlechner]

so in the end, adaptify seems to silently require f# 6.0 at runtime, and our introspection code is not robust to problems like this by printing thousands of errors till it finally crashes. I think proper exception handling could be integrated easily. finding out where all those prints come from is bonus.
