## Number_bin.cyan
package metaobjectTest


@doc{*
    This is a literal number annotation, an identifier follows a literal
    number. The syntax for this annotation is
         nbin or nBin or nBIN
    in which 'n' is a literal number in base 2. 'n' can have numbers and
    underscores but it should start with a number (otherwise the
    compiler will consider it as an identifier). The metaobject uses method

## Number_base.cyan
package metaobjectTest


@doc{*
    This is a literal number annotation, an identifier follows a literal
    number. The syntax for this annotation is
         n_base_N  or n_BASE_N  or n_Base_N
    in which 'n' is a literal number in base 2 to 36 and N is the literal
    number that is the base, in base 10. 'n' can have numbers, underscores, and letters
    but, if it has letters, it should start with a number (otherwise the

## Printexpr.cyan
package metaobjectTest


@doc{*
    Macro printexpr has the following syntax:
        printexpr expr;

    'printexpr' is a macro keyword and 'expr' is an expression. ';' should
    end the macro call.
    The macro call

## Assert.cyan
package metaobjectTest


@doc{*
    Macro 'assert' has the following syntax:
         assert expr;
    'assert' is a macro keyword and 'expr' a Cyan expression. A ';'
    should end the macro call.
    At runtime, if 'expr' is false, an error message is issued.
    The program is NOT terminated.

## Log.cyan
package metaobjectTest


@doc{*
    Annotation 'log', when attached to a prototype P, without paramters,
    adds a statement to each method 'm':
        "Calling method 'm' of prototype 'P'" println

    The same result is got by attaching 'log' to method 'm'


## String_n_N.cyan
package metaobjectTest


@doc{*
    This is a literal string annotation, an identifier precedes a literal
    string. In the string, escape characters are not considered.
    The algorithm used for not-escaping the characters is not perfect.
    It only considers letters such as \n and \r. An alternative to
    this metaobject is to use triple quotes:
          assert """\n""" == n"\n";

## String_r_R.cyan
package metaobjectTest


@doc{*
    This is a literal string annotation, an identifier precedes a literal
    string. The string should be a regular expression as expected by
    prototype cyan.lang.RegExpr. The same regular expression language
    is used by java.util.regex.Pattern. The annotation
        r"regexpr"   or R"regexpr"
    is replaced by

## KeepValue.cyan
package metaobjectTest


@doc{*
  Annotation 'doc' can be attached to any declaration, including
  the program and packages

  This metaobject generates code that writes to a file the value
  of a local or field that is parameter to the annotation.
  In fact, the last five values of the variable are kept in the file,
