syntax error loading ppx_deriving.std in rtop

[ghost]

Is there a way to get ppx_deriving to work in rtop? When I try to load ppx_deriving.std I just get a syntax error:

Reason # #require "ppx_deriving.std";
Error: Syntax error
Reason #

What's interesting is that the following does not cause a syntax error:

 #require "ppx_deriving.asdf";

I wonder if ppx_deriving.std is the code throwing the syntax error? Does everything compile with ppx_deriving.std when not used in the top level?

Yeah, it seems to work okay if you just do #require "ppx_deriving"; too.

Yeah it works fine if I just compile to a binary and run that way.

I should clarify that #require "ppx_deriving"; doesn't throw an error, but in fact #require "ppx_deriving.std"; is necessary to load the library I need since it contains the drivers.

Another thing is that if I compile using reason syntax with rebuild but load utop instead everything works okay. So it's definitely something about the interaction between ppx_deriving and rtop.

I see, okay thanks.
