You can use https://github.com/erning/gorun as a Go script runner. It lets you embed `go.mod` and `go.sum` and have dependencies in Go scripts. This is more verbose than Python's inline script metadata and requires manual management of checksums. gorun caches built binaries, so scripts start quickly after the first time.

Example:

  #! /usr/bin/env gorun
  //
  // go.mod >>>
  // module foo
  // go 1.22
  // require github.com/fatih/color v1.16.0
  // require github.com/mattn/go-colorable v0.1.13
  // require github.com/mattn/go-isatty v0.0.20
  // require golang.org/x/sys v0.14.0
  // <<< go.mod
  //
  // go.sum >>>
  // github.com/fatih/color v1.16.0 h1:zmkK9Ngbjj+K0yRhTVONQh1p/HknKYSlNT+vZCzyokM=
  // github.com/fatih/color v1.16.0/go.mod h1:fL2Sau1YI5c0pdGEVCbKQbLXB6edEj1ZgiY4NijnWvE=

  // <<< go.sum

  package main

  import "github.com/fatih/color"

  func main() {
      color.Green("Hello, world!")
  }

The shebang line can be replaced for compatibility with standard Go tooling:

  /// 2>/dev/null ; gorun "$0" "$@" ; exit $?
  //
  // go.mod >>>
  // ...
