<p>
Within a parenthesized <code>const</code> declaration list the
expression list may be omitted from any but the first ConstSpec.
Such an empty list is equivalent to the textual substitution of the
first preceding non-empty expression list and its type if any.
Omitting the list of expressions is therefore equivalent to
repeating the previous list.  The number of identifiers must be equal

	for _, tok := range macro.tokens {
		if tok.ScanToken != scanner.Ident {
			tokens = append(tokens, tok)
			continue
		}
		substitution := actuals[tok.text]
		if substitution == nil {
			tokens = append(tokens, tok)
			continue
		}
		tokens = append(tokens, substitution...)
	}
	in.Push(NewSlice(in.Base(), in.Line(), tokens))
}

		if r.Name.Kind == "func" {
			switch r.Context {
			case ctxCall, ctxCall2:
				functions[r.Name.Go] = true
			}
		}

		expr := p.rewriteName(f, r, false)

		if *godefs {
			// Substitute definition for mangled type name.
			if r.Name.Type != nil && r.Name.Kind == "type" {
				expr = r.Name.Type.Go
			}
			if id, ok := expr.(*ast.Ident); ok {
				if t := typedef[id.Name]; t != nil {

Instantiation proceeds in two steps:

<ol>
<li>
Each type argument is substituted for its corresponding type parameter in the generic
declaration.
This substitution happens across the entire function or type declaration,
including the type parameter list itself and any types in that list.
</li>

<li>
After substitution, each type argument must <a href="#Satisfying_a_type_constraint">satisfy</a>
