Literals & Comments

Most of this will be familiar to users of other languages, but see particularly string interpolation, code quoting and comments.

Numbers

Integers are any series of digit characters [0-9], and are 64-bit by default.

x = 1500
x = 75

A series of digits with a . is a Float64.

x = 2.0
x = 3.141

Strings start with ", and end at the next ".

s = "Hello, World!"

Code quotations begin at `, and end at the next `.

ex = `foo(a, b)`

Symbols are quoted variables.

sym = `Foo`

Single line comments start with #.

println("Hello, World!") # this is a comment

Multi-line and internal comments start with #| and end with |#. They can be nested.

println("Hello, World!") #| This is a
  multi line comment |#

3 + #| this is an internal comment |# 4

#| this is a #| nested |# comment |#
