does bash have anything like lambda?

I want to define and call a function without saving it for later. Is this possible in bash?

If not, can anyone think of a way to write it?

function foo {
    echo "doing foo stuff"
}
foo arg1 arg2 arg3
unset -f foo
# now foo is no longer defined

And to get a more lambda-like feel:
eval "function foo { echo 'doing foo stuff'; }"
foo
unset -f foo
