Topic: Trouble defining a function in the REPL

Liam Dyer (Jun 23 2023 at 20:05):

Did some browsing of the tutorial and wanted to try out some stuff in the REPL

» f = \n -> n * 2
── MISSING FINAL EXPRESSION ────────────────────────────────────────────────────

I am partway through parsing a definition, but I got stuck here:

1│  app "app" provides [replOutput] to "./platform"
2│
3│  replOutput =
4│      f = \n -> n * 2
                       ^

This definition is missing a final expression. A nested definition
must be followed by either another definition, or an expression

    x = 4
    y = 2

    x + y

I got this, so I thought maybe I was doing something wrong so I directly copied the example from the tutorial for defining funcitons.

» addAndStringify = \num1, num2 ->
…     Num.toStr (num1 + num2)
── MISSING FINAL EXPRESSION ────────────────────────────────────────────────────

I am partway through parsing a definition, but I got stuck here:

1│  app "app" provides [replOutput] to "./platform"
2│
3│  replOutput =
4│      addAndStringify = \num1, num2 ->
5│          Num.toStr (num1 + num2)
                                   ^

    x = 4
    y = 2

    x + y

Am I messing something up or is this a bug?
