Additional context

I would expect Temporary token to be part of RangeVar node but parser still panics so I had to make it part of ViewStmt, very similar to what we had with the As token being part of CreateDomainStmt in #61

btw @cvng feel free to add your sample statements do tests/data/statements/valid to also include them in the e2e tests!

I will do, I find it generally more convenient to debug at the e2e layer
