    Looks like one needs additional underscore:
    ${^_MYDEBUG} = 1;

    "No name that begins with ^_ will acquire a special meaning in any future version of Perl; such names may therefore be used safely in programs. $^_ itself, however, is reserved."

    "In particular, the special ${^_XYZ} variables are always taken to be in package main , regardless of any package declarations presently in scope."
