Source: delegatize.d

Expression `toDelegate`(Expression `e`, Type `t`, Scope* `sc`);
  Convert expression into a delegate.
  Used to convert the argument to a lazy parameter.
  Parameters:

  Expression `e` | argument to convert to a delegate
  Type `t` | the type to be returned by the delegate
  Scope* `sc` | context

  Returns:
  A delegate literal
bool `lambdaCheckForNestedRef`(Expression `e`, Scope* `sc`);
  Look for references to variables in a scope enclosing the new function literal.
  Essentially just calls checkNestedReference() for each variable reference in `e``.
  Parameters:

  Scope* `sc` | context
  Expression `e` | expression to check

  Returns:
  `true` if error occurs.
bool `ensureStaticLinkTo`(Dsymbol `s`, Dsymbol `p`);
  See if context `s` is nested within context `p`, meaning it `p` is reachable at runtime by walking the static links. If any of the intervening contexts are function literals, make sure they are delegates.
  Parameters:

  Dsymbol `s` | inner context
  Dsymbol `p` | outer context

  Returns:
  `true` means it is accessible by walking the context pointers at runtime
