Worrying to see

Map<String, Integer> myMap = ["$name": 25] // or [(name): 25]

Being recommended

Which is indeed wrong since the key here is a GString not a String.

since GString there is almost always wrong, shouldn't we require the
expression syntax here as well... meaning ("$name") ?

Not sure I understand what you mean: disallowing GStrings as keys?

How about calling toString on GStrings that used as literal map keys?

that would imho cause an expectation for [("$name"):1] also have a
String key. Also it causes problems in case of map["$name"], where one
could expect toString as well
