Running `fpp-check` on this model results in a crash: ``` struct S { x: F32 x: U16 y: U32 } ``` The code here should use `Result.foldLeft` instead of `foldLeft`: https://github.com/nasa/fpp/blob/c1a7b7e4dd0e0771686d208c58ec7c2a720170ff/compiler/lib/src/main/scala/analysis/Analysis.scala#L481 Thanks to @timcanham for reporting this!
