Do you mean like:
org.conman.syslog('debug',"We have reached here")
-- 'debug' being LOG_DEBUG
or
magic = org.conman.fsys.magic('mime','debug')
-- flags to magic_open()
-- MAGIC_MIME and MAGIC_DEBUG
or
addr = org.conman.net.address('127.0.0.1','tcp','www')
-- 'tcp' and 'www' are integer constants
or
sock = org.conman.net.socket('ip','tcp')
-- same for 'ip' and 'tcp' here too!
or
sock.reuseaddr = true
-- really SOL_SOCKET and SO_REUSEADDR in one
-- hidden call to setsockopt().
or
org.conman.process.limits.soft.core = "20m"
-- the integer constant here is RLIMIT_CORE
-- to setrlimit() way behind the scenes,
-- which, by the way, we're limited to 20
-- megabytes
-spc (I tend to use string literals quite a bit ... )
