Good point.

While I never use these constants for anything other than setting variables I declare, it would be easy to use them otherwise. I started this habit when I was first learning perl as a way of distinguishing "logical" and "numerics" in my code and for setting "logical" options in some modules (like DBI).

For example:

$gDBHandle = DBI->connect ( 'dbi:Oracle:' . ORATNS, ORAUSER, ORAPASS, { AutoCommit => FALSE, PrintError => FALSE, RaiseError => FALSE, } ) || die 'Could not connect to Oracle ['.$DBI::errstr.' - '.$DBI::er +r.']';
This just helped me remember I was turning "off" those options instead of setting some "numeric" to zero.

Thank you for the suggestion.

[Corion]: marto: Naah, my module doesn't care, but the users of my module might expect some things to work in Chrome that only work in later builds (or, as seems to be the case, don't work there either ;) )
[Corion]: But I really wonder - I can tell Chrome to go offline, but requesting pages over the network still succeeds. But if I manually click the "offline" checkbox, that's different :-/
[LanX]: Corion can you tell WMC to check the sub version number ?
