I'm writing this mail without reading current zend code.

Anyway, is it feasible to raise E_DEPRECATE without much performance
penalty?
For example,

if (!strcmp(name, name_to_be_searched)) {
  do_something;
} else if (!strcasecmp(name, name_to_be_searched) {
  rase_error;
  do_something;
}

Duplicated codes may be removed by macro. strcasecmp() checks may be removed
10 years later or more.

Regards,
