Thanks for the explaination.
I plan to move to 2.0 as soon as I can. In the meantime, tsc is logging an error for me. I worked around it on my side by changing the options for the code generator that creates the JSON schema I am inputting.

This is not a bug, but a behavior in TS<2.
- In TS<2, void is subtype of all types, and there are no named
nullandundefinedtypes - In TS>=2 in strict null check mode:
- void is still a subtype of all types
neveris a subtype of all typesnullis a subtype ofanyundefinedis a subtype ofanyandvoid
At most, we should add a readme note here. Biting my tongue, I expect that in a few months most people will have switched onto TS2.

If you're curious, see microsoft/TypeScript#7140 and microsoft/TypeScript#8652 - these have not yet made it into the language spec.

FYI: If someone comes across this, I am on typescript 2.0.3 and I can confirm this is no longer an issue.
