To make this look nicer, you can also write
(foo '(flag1 flag2 someotherflag))
Another option are keyword arguments, like
(foo :flag1 #t :flag2 #t :someotherflag #t)
There is no C

Various things in the guile core are done like that, stuff like O_RDWR
for `open'. The list of symbols Ludovic described is done in the
guile-gtk interface and works nicely t

You can make the flags available to scheme as numbers, and then the
Scheme users can use Guile's b

Hello,
I'm sure this is a very basic question about passing "or-able" flags to
a function. In C I might do something like:
#define FLAG_FOO 1
#define FLAG_BAR 2
#define FLAG_BAZ 4
myfn(int flags)
{
if (flags & FLAG_BAR)
printf ("bar flag is set\n");
...
}
and then call myfn
