I would like to create my own subroutines which would work the same way as print FILEHANDLE LIST works.

Is there any non-magic way to create a subroutine with an optional first argument? Or would that just create confusion in code?

The sub in question would be used to send a job into a queue. In most circumstances, there is only one queue. But there could be others. And the sub takes only one argument.

example: 

queue $job;
queue OTHER_QUEUE $job;
