solidity 0.5: breaking change

[mattiaerre]

as per @maxsam4 comment on Gitter:

The JSON AST field isConstructor of the FunctionDefinition node was replaced by a field called kind which can have the value "constructor", "fallback" or "function". this is also a breaking change.

I'm not sure I understand this issue. Do we have an example of code that makes prettier fail?

no longer an issue; closing it
