Escape character on map interpreter

[adhi-goel]

I have a map[string]string with URL host:port defintions as values. Is it possible to escape the : in the url so the map can be read? Basically want to interpret this:
ORG_URLS: "org1:host1\:5051, org2:host2\:5051"
as:

map[string]string{
    org1: "host1:5051",
    org2: "host2:5051",
}

I can't change the envKeyValSeparator because there are other env variables that use : as the separator and they've already been deployed. It'd be more work to change all those variables for each deployment.

hmmm not sure, might need some extra work around it.

If it's implemented, it'd be a big help!

it just works, don't need to escape:

func TestIssue369(t *testing.T) {
	t.Setenv("MAP", "s1:foo:9123,s3:bar:3333,s2:zaz:9999")

	type Config struct {
		Map map[string]string `env:"MAP"`
	}

	var cfg Config
	isNoErr(t, Parse(&cfg))
	isEqual(t, map[string]string{
		"s1": "foo:9123",
		"s2": "zaz:9999",
		"s3": "bar:3333",
	}, cfg.Map)
}

Looks a v10 vs v11 issue. I was getting the following on v10:

panic: env: parse error on field "Map" of type "map[string]string": "s1:foo:9123" should be in "key:value" format

Is v11 backwards compatible with v10 provided it's Go 1.18+? Is there a changelog?

as far as i remember should be yes.

Thank you!
