This module requires PHP5 but doesn't say so?

I tried enabling this module on a D6 test site, to try out some new update.module functionality and fixes I'm working on (http://drupal.org/node/197186). As soon as I enabled it, I was getting syntax errors like so:

Parse error: parse error, expecting `T_OLD_FUNCTION' or `T_FUNCTION' or `T_VAR' or `'}'' in .../sites/all/modules/open_flash_chart_api/open_flash_chart_api.module on line 83

My site is PHP 4.4.7. I'm guessing this module depends on PHP5. If so:

A) You should clearly state this on the project node.
B) The .info file should specify this requirement. See http://drupal.org/node/114774#info-php

Thanks,
