Antiquoted

Constructors

Constructor	Fields	Description
`Plain`	`contents: v`	Literal value: `Text` in string parts, `String` in `DynamicKey`
`Antiquoted`	`contents: Expr`	Embedded expression `${...}`
`EscapedNewline`	(none)	Escaped newline `\` in indented strings

Antiquoted is polymorphic in the Plain constructor. It is used at two type arguments:

Antiquoted Text: in string parts (DoubleQuoted / Indented), Plain wraps literal text.
Antiquoted String: in DynamicKey, Plain wraps a String AST node (DoubleQuoted / Indented).

A string like "hello ${x} world" becomes a list: [Plain "hello ", Antiquoted (Sym "x"), Plain " world"]

syntax.mkPlain "hello"       # text content (string parts)
syntax.mkAntiquoted (syntax.mkSym "x")
syntax.mkEscapedNewline
