/// Create an instance of `MessageContext`.

/// The `locales` argument is used to instantiate `Intl` formatters used by

/// Examples:
///
/// const ctx = new MessageContext(locales);
///
/// const ctx = new MessageContext(locales, { useIsolating: false });
///
/// const ctx = new MessageContext(locales, {
/// useIsolating: true,
/// functions: {
/// NODE_ENV: () => process.env.NODE_ENV
/// }
/// });
///
/// Available options:
///
/// - `functions` - an object of additional functions available to
/// translations as builtins.
///
/// - `useIsolating` - boolean specifying whether to use Unicode isolation
/// marks (FSI, PDI) for bidi interpolations.
///
/// - `transform` - a function used to transform string parts of patterns.
