note 18246 added to language.variables.variable

Is there a way to use a variable as a function name if the function is a PHP built-in? I've tried: $print_fn = 'print'; ${$print_fn("print this")}; which results in: Fatal error: Call to undefined function: print() in blah If I do the same thing with a user-defined function: function mprint($arg_value) { print $arg_value; } $print_fn = 'mprint'; ${$print_fn("print this")}; I get the output expected + much joy.
