The attached patch moves the common elements of loose_embedding[]
and strict_embedding[] to a macro so they can be maintained in
one place. As Tom Lane noticed, ::_plperl_to_pg_array was missing
from strict_embedding[], which appears to be a bug.

I'm not sure this patch meets Tom's request to avoid "too much
violence to the readability," mostly because of the added backslashes
at the end of the macro's lines. Opinions?
