work on write_stmt translation
reorder some translation actions (esp. re: error checking) in process()
pass current node's env through for internal parses
pass *copy* of env into internal parser (is this enough for all cases?)
better sms$ignore region env push/pop; do not translate internal string writes
add function_stmt type/kind to env; pass node env into raw() parse, no deepcopy
add two tests against recent bug fixes
update IDENTITY
