If no required module provides pkg, an error would be reported. 'go install pkg' within a module would install pkg at the version required in the module's go.mod.There are several more restrictions: all arguments must refer to packages in the same module at the same version, and its go.mod must not contain replace directives or anything else that would cause it to be interpreted differently than if it were the main module.I've updated that proposal to use 'go install', and added examples and rationale. This takes the place of 'go get -b' in #40276.It would always run in module or would report an error if GO111MODULE=off. It would ignore the go.mod in the current directory, if there is one. 'go install would install pkg at version.It must not contain directives that would cause It to be interpreted differently than if it were the main module.
