Informix does this nicely:
UNLOAD TO "file"SELECT *FROM tab

Merging COPY and SELECT has some real advantages.  You can specify
columns, parts of a table using WHERE, and even joins.  Very flexible.

Perhaps, if the table name is missing from COPY, we can allow a SELECT:
COPY TO 'file'SELECT *FROM tab
