Typescript@next removed/renamed TypeVariable

[deregtd]

When using tsutils with the latest Typescript (typescript@next, currently 2.8.0-dev.20180221), they appear to have renamed the TypeVariable interface to InstantiableType. This changed somewhere between commits afc588eb9e6322faf55bc28f26994712e3f02261 and edffb120549536cefd73409cc87f0439dac722cf but I didn't dig deep enough to see where.

If you simply change ts.TypeVariable to ts.InstantiableType in typeguard/type.ts, that fixes the compile error in tsutils, but I don't know if that has other side effects that need investigating, or if you want to rename the checks as a result of the TS renaming.

Thank you for the report. Unfortunately there's no easy way to fix this for you.
If I change the public API to be compatible with the upcoming typescript@2.8, it will break everyone else who's still using the latest release 2.7.2

I could however publish a new version as tsutils@next until typescript@2.8.1 is released.

in the meantime you could set skipLibCheck: true in your compilerOptions.

Doing an @next would be awesome. I had to pull in tslint@next as well to fix some other issues with our lint rules, so it looks like in 2.8 they're changing some stuff that everyone's getting ready for. :)

I'll work on this today and keep you posted here.
I'm a bit puzzled about the tslint@next thing, though ... There was no activity at all in the TSLint repo since the last stable release. tslint@next is v5.0.0-dev which is pretty old to say the least.

Oh right in the end I went up to 5.9.1 + tslint-microsoft-contrib 5.0.3 and that fixed the actual problem. I tried @next and that fixed one problem (compared to the version I was at), then had to bump again to 5.9.1 to get rid of the last of the issues. Ignore me on that. :)

@deregtd I actually found a way to make this fix backwards compatible. I just published v2.21.2 which compiles fine with typescript@next

Works great, thanks so much for the quick turnaround!
