22:33 <mihoshi> Sirp:Btw, how can one check in WML that variable is not set?
22:33 <Sirp> I haven't written anything real in WML for a long time.
22:34 <CIB0> you can't.
22:34 <CIB0> it gets set as soon as you check, lol
22:34 <cycholka> mihoshi: probably by querying foo.length
22:35 <cycholka> if variable is not set foo.length will be equal to 0
22:36 <CIB0> cycholka: no, that only works for arrays
22:36 <CIB0> if foo is a container, it works
22:36 <mihoshi> cycholka: Thanks:)
22:36 <CIB0> if it is a scalar, it doesn't
22:46 <cycholka> boucman: an EasyCodingTask - add bool .is_set parameter to
variable
