State
The state of the REPL contains necessary bindings instead of having to have mutation
The compiler in the REPL needs to do some wrapping in order to compile
valid code. This wrapping occurs when a single MemberDef that cannot be
top-level needs to be compiled. In order to do this, we need some unique
identifier for each of these wrappers. That identifier is objectIndex.
Free expressions such as 1 + 1 needs to have an assignment in order to be
of use. These expressions are therefore given a identifier on the format
resX where X starts at 0 and each new expression that needs an
identifier is given the increment of the old identifier. This identifier is
valIndex.
- Value parameters:
- context
the latest compiler context
- imports
a map from object index to the list of user defined imports
- invalidObjectIndexes
the set of object indexes that failed to initialize
- objectIndex
the index of the next wrapper
- valIndex
the index of next value binding for free expressions
