Nim is simple..

-
-# compute average line length
-var
-  sum = 0
-  count = 0
-
-for line in stdin.lines:
-  sum += line.len
-  count += 1
-
-echo("Average line length: ",
-  if count > 0: sum / count else: 0)
-
-
-
-

..and type safe...

-
-# create and greet someone
-type Person = object
-  name: string
-  age: int
-
-proc greet(p: Person) =
-  echo "Hi, I'm ", p.name, "."
-  echo "I am ", p.age, " years old."
-
-let p = Person(name:"Jon", age:18)
-p.greet() # or greet(p)
-
-
-
-
-
-

C FFI is easy in Nim..

-
-# declare a C procedure..
-proc unsafeScanf(f: File, s: cstring)
-  {.varargs,
-    importc: "fscanf",
-    header: "<stdio.h>".}
-
-# ..and use it...
-var x: cint
-stdin.unsafeScanf("%d", addr x)
-
-

Compile and run with:
    $ nim c -r example.nim

-
-
-

..and DSLs are too...

-
-# a simple html server
-import
-  jester, asyncdispatch, htmlgen
-
-routes:
-  get "/":
-    resp h1("Hello world")
-
-runForever()
-
