Hello, thanks for your amazing work on tinygo! I am facing an issue accessing `IsExported` method from the reflect package ## Minimal steps to reproduce: 1. Write this program: ``` package main import ( "reflect" ) func main() { if reflect.TypeOf(0).Method(0).IsExported() { println("IsExported exists") } } ``` 2. Run `tinygo build .` ## Expected result To compile and build ## Actual result Error: ``` main.go:8:33: reflect.TypeOf(0).Method(0).IsExported undefined (type reflect.Method has no field or method IsExported) ```
