command line args to guile

[Rick Taube]

im trying to start guile and have it both eval an expr and load files 
when it starts.
is there a command switch like -c  that will eval an expression but NOT 
exit guile?
when i do guile --help i dont see it. id like to do something like:

% guile -c '(define foo 1)' -l "bar.scm" -l "bif.scm"
guile> foo
1

so that the define happens before the loading.
but the -c  switch exits.


I then tried working with the -e option that takes a function but i 
guess i do not understand
how to notate a lambda expr from the shell:

% guile -e '(lambda args (display args))'
ERROR: Unbound variable: #{\(lambda\ args\ \(display\ args\)\)}#

im not sure how to notate it so that guile reads it as a lambda  expr 
and calls it.
any help would be appreciated!
best,
