[Wildcard Variables] Experiment Flag about sdk HOT 2 OPEN

cc. @dart-lang/language-team if you have any other suggestions and/or opinions.

Sure, we can name it wildcard-variables. I'll change the issue names and labels for the feature.

from sdk.

Suggestion: Name the experiment flag wildcard-variables, or non-binding-variables. (Probably the former, it's a better name.)

"Wildcards" by itself is little too vague (I can imagine several different features that could use that name, most involving types. (Imagine being allowed to write * for an unconstrainted type in both covariant and contravariant position, so * Function(*) is all unary functions. I'd call that a wildcard type.)

Possibly also use wildcard-variables for the feature itself (github labels, documentaton). If we're going to be referring to it by name for years, it's better to have a name that's unlikely to clash with a later feature name.
