Inconsistencies with JSON casting in interpreter/compiler

[LilyMakesThings]

Self explanatory. The Interpreter uses methods to ensure that objects and arrays retain their formatting and aren't "stringified" in the traditional sense.
This is done because it's the most logical for people using the new types.

This does not carry over into the compiler.

This is the value of the list reporter, if you're curious.

This is not an issue for extensions, as those are running under a compatibility layer which accounts for the expected methods.

Fix: use a different toString method
