METHODS
  blessed
        [%

                EXPR.method(args);
            END;
        %]

    Returns the name of the package if "EXPR" is a blessed reference.

  dualvar
        [% SET dv = ScalarUtil.dualvar( num, string ) %]

    Returns a scalar that has the value "num" in a numeric context and the
    value "string" in a string context.

  isvstring
        [%
            USE vstring = format('%vd');
            USE string = format('%s');

            IF ScalarUtil.isvstring(EXPR);
                vstring(EXPR);
            ELSE;
                string(EXPR);
            END;
        %]

    Returns true if "EXPR" was coded as vstring;

  looks_like_number
        [% IF ScalarUtil.looks_like_number(EXPR) %]
            [% EXPR %] looks like number
        [% END %]

    Returns true if perl thinks "EXPR" is a number.

  openhandle
        [% IF ScalarUtil.openhandle(FH) %]
            FH is an opened filehandle
        [% END %]

    Returns "FH" if it is opened filehandle, "undef" otherwise.

  refaddr
        [% ScalarUtil.refaddr(EXPR) %]

    Returns internal memory address of the "EXPR" if it is a reference,
    "undef" otherwise.

  reftype
        [% SWITCH ScalarUtil.reftype(EXPR) %]
            [% CASE 'ARRAY' %]
                [% EXPR.size %]
            [% CASE 'HASH' %]
                [% EXPR.list.size %]
        [% END %]

    Returns the type of the "EXPR" if it is a reference, "undef" otherwise.

  tainted
