Issue with generated code for p5js types

[tabakerov]

I have @types/p5 (1.3.0) module in my project and ts2fable v0.7.1
I do

ts2fable node_modules/@types/p5/index.d.ts src/P5.fs -e p5

and I have

.../src/P5.fs(95,17): (95,24) error FSHARP: The namespace or module '__index' is not defined. (code 39)

in the generated P5.fs
