That's the only sane way I can think of.

this will have side-effects you may not like.
the entry www.domain.com will also have an SOA record, NS records and 
other records you set up
for domain.com
The best way is to always use A records
www.domain.com.      IN   A   127.0.0.1
ftp.domain.com.      IN   A 127.0.0.1
mail.domain.com.      IN   A   127.0.0.1

You can use CNAME to point from one host entry to another
ftp.domain.com.      IN   CNAME   www.domain.com.

Illegal, as already pointed out.
CNAME's cannot have any other data assigned to the RR
