Identifier names

Every identifier has a unique name, which is used to refer to it.

A name can be as long as you like. It must begin with a letter or the underscore character ( _ ). After that can be any mixture of letters, underscore and digits.

Upper case and lower case letters are considered distinct, so the identifiers M3i, m3i, m3I, and M3I are different.

Magma reserved words are not allowed as identifier names.

The name _ is not allowed as an ordinary identifier name because _ is the throwaway identifier.
