Yes, but I adore the simple syntax.

    inl add a b = a + b

is basically a macro #define add(a,b) a+b

    inl f = add 1

is a macro #define f add(1)

    f 2, f 3

but e.g.

    inl f = add c

would create a closure to capture c. inl would guarantee that the capturing is lexical, not dynamic.

There's no need for the comma operator in args, comma is to create lists.

Similarly, Haskell would be:

    add = (+)
    f = add 1
    f 2

This kind of syntax is great for small code samples or to play in a CLI, but in larger programs more traditional (verbose) syntax works better for me. YMMV.
