How can I concatenate regex literals in JavaScript?

Is it possible to do something like this?

var pattern = /some regex segment/ + /* comment here */
    /another segment/;

Or do I have to use new RegExp() syntax and concatenate a string? I'd prefer to use the literal as the code is both more self-evident and concise.

I prefer to use eval('your expression') because it does not add the /on each end/ that ='new RegExp' does.
