No it doesn't - "string starts with xyz" would be "/^xyz/" which
coincidentally avoids your problem of xyz being interpreted as a
variable name.
More generally, if you don't want $xyz interpreted as a variable, then
use single quotes - or if you must use double quotes, then escape the
$ with a backslash.
