-# Variables
-
-Nimrod supports three different types of variables, `let`, `var`, and `const`. As with most things, multiple variables can be declared in the same section.
-
-``` nimrod
-proc getAlphabet(): string =
-  result = ""
-  for letter in 'a'..'z':
-    result.add(letter)
-
-# Computed at runtime
-const alphabet = getAlphabet()
-
-# Mutable variables
-var
-  a = "foo"
-  b = 0
-  # Works fine, initialized to 0
-  c: int
-
-# Immutable variables
-let
-  d = "foo"
-  e = 5
-  # Compile-time error, must be initialized at creation
-  f: float
-
-# Works fine, `a` is mutable
-a.add("bar")
-b += 1
-c = 3
-
-# Compile-time error, const cannot be modified at run-time
-alphabet = "abc"
-
-# Compile-time error, `d` and `e` are immutable
-d.add("bar")
-e += 1
-```
-
-``` console
-$ nimrod c --verbosity:2 ./variables.nim
-variables.nim(18, 2) Error: 'let' symbol requires an initialization
-    e: float
-    ^
-```
-
-Without `--verbosity:2` only the error will be shown without the position cursor.
-
-## Const
-A `const` variable's value will be evaluated at compile-time, so if you inspect the C sources, you'll see the following line:
-
-``` c
-STRING_LITERAL(TMP129, "abcdefghijklmnopqrstuvwxyz", 26);
-```
-
-The only limitation with const is that compile-time evaluation cannot interface with C because there is no compile-time foreign function interface at this time.
