If

Fields

branches: Vec<Branch>

else_body: Option<Script>

redirs: Vec<Redir>

DoubleBracket

Fields

words: Vec<Word>

redirs: Vec<Redir>

Case

case WORD in PATTERN) BODY ;; … esac (POSIX 2.9.4.3). Which arm runs depends on a value resolved at runtime, so — like Cmd::If — every arm body is classified and the command is only as safe as its worst arm.

Fields

subject: Word

arms: Vec<CaseArm>

redirs: Vec<Redir>

FunctionDef

name() { body } (or function name { body }). Defining a function has NO effect — it is classified Inert. The body’s safety matters only when the function is CALLED (resolved in check), so it is stored, not flattened.

Fields

name: String

body: Script
