Can psql access environmental variables or command line params?

Nice trick, but when I try the following variant:
psql -v TEST=16 -c 'select :TEST as "input"'
I get
ERROR: syntax error at or near ":"
LINE 1: select :TEST as "input"
This seems to be contrary to the psql manual page:
These assignments are done during a very early stage of start-up...
psql manual page:
-c command
--command command
Specifies that psql is to execute one command string, command,
and then exit. This is useful in shell scripts.
command must be either a command string that is completely
parsable by the server (i.e., it contains no psql specific
features), or a single backslash command. Thus you cannot mix
SQL and psql meta-commands with this option.
