Much of this proposal is cribbed from proposals @ahmetb has previously made, ideas are not my own.

Expected Behavior

Users have an easy cruft-free way to express a multi-statement script in the body of a Task step, without having to understand advanced topics about containers, like what an entrypoint or a command is.

Users should only need to have passing familiarity with a shell environment to be successful using Tekton.

Actual Behavior

View main.go
package main
import "fmt"
func main() {
fmt.Println("hello world")
View main.go
package main
import "fmt"
func main() {
fmt.Println("goodbye cruel world")
