=over =item evalbytes EXPR X =item evalbytes This function is like L with a string argument, except it always parses its argument, or C<$_> if EXPR is omitted, as a string of bytes. A string containing characters whose ordinal value exceeds 255 results in an error. Source filters activated within the evaluated code apply to the code itself. This function is only available under the C feature, a C (or higher) declaration, or with a C prefix. See L for more information. =back
