No such syntax is supported unless you want to roll your own function
and tokenizer.  slsh provides an example of this as is indicated by its
help command:

slsh> help
Most commands must end in a semi-colon.
If a command begins with '!', then the command is passed to the shell.
  Examples: !ls, !pwd, !cd foo, ...
Parenthesis are automatically added if the first word is a function and
is followed by a ','.  For example:
  plot, 1, 2;color="red"  ==>  plot(1,2;color="red");
Special commands:
  help <help-topic>
  apropos <something>
  start_log( <optional-log-file> );
    start logging input to a file (default is slsh.log)
  stop_log();
    stop logging input
  save_input (<optional-file>);
    save all previous input to a file (default: slsh.log)
  who;
    show a list of locally defined variables and functions
  quit;

The implementation is in slsh/lib/slshrl.sl.

I hope this helps,
