@bobzhang In BS7, the following worked: ```reason [@bs.inline] let x = 42.; ``` In BS8, it does not work anymore, I get the error message ``` invalid payload in bs.inline ``` Revisiting the original issue, I found that you were saying "currently support bs.inline for boolean/int/string" (https://github.com/BuckleScript/bucklescript/issues/3472#issuecomment-480799386). So it seems this was only working for floats "by coincidence" in BS7. Still, would be nice to have it in BS8.
