Literals

• Integers (non-decimal bases prefixed by the decimal base and r)
• Floats (all the usual forms)
• Strings (including embedded C-like escape sequences) enclosed in single quotes:

	'a string'
	'an embedded \' quote'
	''			the empty string
	'lots\tof\nstrange\r\\characters\0'

The comment convention is to surround the comment string with double quotes:

	"this is a comment"

self and resend are the only reserved identifiers.

Identifiers can contain any letter, digit or underscore, and must start with a small letter. Case is significant.
