Enum SubSigParam 

pub enum SubSigParam {
    Scalar(String, Option<PerlTypeName>, Option<Box<Expr>>),
    Array(String, Option<Box<Expr>>),
    Hash(String, Option<Box<Expr>>),
    ArrayDestruct(Vec<MatchArrayElem>),
    HashDestruct(Vec<(String, String)>),
}

Named parameter in sub name (SIG ...) { } — stryke extension (not Perl 5 prototype syntax).

Variants

Scalar(String, Option<PerlTypeName>, Option<Box<Expr>>)

$name, $name: Type, or $name = default — one positional scalar from @_, optionally typed and/or with a default value.

Array(String, Option<Box<Expr>>)

@name or @name = (default, list) — slurps remaining positional args into an array.

Hash(String, Option<Box<Expr>>)

%name or %name = (key => val, ...) — slurps remaining positional args into a hash.

ArrayDestruct(Vec<MatchArrayElem>)

[ $a, @tail, ... ] — next argument must be array-like; same element rules as algebraic match.

HashDestruct(Vec<(String, String)>)

{ k => $v, ... } — next argument must be a hash or hashref; keys bind to listed scalars.
