HyperFun: Comments, Names, Case Sensitivity
Throughout the description, all reserved ("key") words and literals will be surrounded by apostrophes `...'.
Any text beginning from
'--' to the end of the current line will be
ignored by the parser.

All names appearing in HyperFun program (names of objects, local numeric variables and functions) can consist of letters, digits and underscore character '_' (that is not considered a letter!), but the first character must be a letter.
The text of a program in HyperFun is case-insensitive. So the following pairs of names are equivalent:
HyperEllipsoid and hyperellipsoiD
COS and cos
Xx and xX
