Enum CasePattern 

pub enum CasePattern {
    Any,
    Literal(Word),
    Expanded(Word),
}

One case alternative.

Bash matches these as filename-style patterns. This shell matches literal text instead, for the same reason builtins’ grep and sed take literal patterns: a partial wildcard is the pattern a literal matcher answers wrongly and silently, so it is rejected by name rather than quietly mismatched. A bare * is kept, because it is the default branch rather than a wildcard in any meaningful sense.

Variants

Any

A bare *: the catch-all branch, which matches every subject.

Literal(Word)

A constant pattern, already checked for pattern syntax when it was parsed.

Expanded(Word)

A pattern built from expansions, checked for pattern syntax when it is expanded.

It cannot be checked earlier, because its text does not exist until the script runs — the same reason grep "$pattern" is checked at run time rather than at parse time.
