Parentheses can be used as an expression, but they do not provide end of statement inference, so it is necessary to place semicolons yourself.
``` nimrod
square((
var result = newSeq[float]();
for i in 0..1000:
result[i] = i;
result
))
```
An interesting and unexpected side effect of this syntax is that Nimrod is suitable even for brace purists!

Nimrod many different control flow constructs, including the standard `if`s, `else`s, and `while`s. However, Nimrod does not use an `else if` construct like many languages, it uses a more condensed `elif`.
Nimrod has many different control flow constructs, including the standard `if`s, `else`s, and `while`s. However, Nimrod does not use an `else if` construct like many languages, it uses a more condensed `elif`.
When inside a loop, `continue` can be used to skip the rest of the loop body and to begin the next iteration; `break` can be used to immediately leave the loop body.

@ -8,9 +8,9 @@ Nimrod has several primitive types:
* signed integers: `int8`, `int16`, `int32`, `int64`, and `int`, where `int` is the same size as a pointer
* unsigned integers are similar with `u` prepended to the type
* floating points numbers: `float32`, `float64`, and `float`, where `float` is the processor's fastest type
* characters: `char`, and basically an alias for uint8
* characters: `char`, which is basically an alias for uint8
To indicate the size of an integer literal, append `u` or `i` and the size you'd like to the end. However, this is not typically necessary.
To indicate the size of an integer literal, append `u` or `i` and the size you'd like to the end. However, usually this is not necessary.
Integers can also have `0[xX]`, `0o`, `0[Bb]` prepended to indicate a hex, octal, or binary literal, respectively. Underscores are also valid in literals, and can help with readability.

Precedence rules are the same as most other languages, but instead of `^`, `&`, `|`, `>>`, `<<`, the `xor`, `and`, `or`, `shr`, `shl` operators are used, respectively.
