This makes it simpler to write explanations in the tex file.
Contexts are necessary to rule out programs where one avraible name is used at multiple types. To capture the intution that statement variables are global, we check statements with a fixed context rather than extending it as new variables are encountered.

These contexts are necessary to catch typing errors where variables
are used with different types at different points in the program.
This version uses a fixed context for statements, with a separate
judgement "gamma is ok" to check for repeated variable names.
