Example: if( ! exists $dg_by_id{$group_id} and $group_id != 0) {}

Lately I've been writing scripts for an application with it's own lighter weight scripting language and a Perl API. The proprietrary language uses syntax such as

$model like /pattern/
$IPaddress in [ 192.168.0.0/24, 192.168.1.0/24 ] and $IPaddress not in
+ [ 192.168.0.1/32, 192.168.1.1/32]

[download]

, etc. Even in Perl scripts, we have to use some of their language to specify filters (like what to/not to run against) in the proprietary language format in a special comment block at the top. So, lately, even in Perl I've found myself writing 'and' instead of '&&" and ditto for 'or'. I'm not as fast to use 'not' instead of '!', but it's tempting. One benefit is for our non-programming users, they can make more sense of the Perl code.

My question is what's the risk/harm in using them like this? There's the low precedence that allows them to work, but I haven't been bitten by that yet (that I know of).
