=over =item evalbytes EXPR X =item evalbytes This function is like L|/eval EXPR> with a string argument, except it always parses its argument, or L|perlvar/$_> 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. L|/evalbytes EXPR> is available only if the L feature|feature/The 'unicode_eval' and 'evalbytes' features> is enabled or if it is prefixed with C. The L feature|feature/The 'unicode_eval' and 'evalbytes' features> is enabled automatically with a C (or higher) declaration in the current scope. =back
