305 Takes three arguments. The first two are references to array of hashrefs, each like:
306 [ { code => 'CODE', value => 'value' }, { code => 'CODE2', value => 'othervalue' } ... ]
308 The third option specifies whether repeatable codes are clobbered or collected. True for non-clobber.
310 Returns one reference to (merged) array of hashref.
