Literals
You can specify a literal by placing it in single or double quotes (for strings), or by typing it in as-is (for numbers, both floating-point and integer). You can get linebreaks with \n, tab characters with \t, and you can also escape the quote character with a backslash.
Examples
"This is a string"
'This is also a string'
'This string shouldn\'t fail'
"This string\nHas a linebreak"
