In #12 (comment) I said we'd need to define the exact behavior of the backslash character \ for the purposes of escaping. This includes defining:

• the list of known escape sequences (\ ( a space), \t, \n, \*, \[, \{, \u, \\, others?),

• how the Unicode escapes work: is \u20 valid and the same as \u0020?

• the behavior of unknown sequences, like \a (does the backslash take the following character out of the syntax parsing?),

• the behavior for edge-cases, like:

    foo\bar = Foobar
  

  Is that a syntax error? If not, what is the name of the identifier?

    foo = Foo\
    bar = Bar
  

  Is that an escaped new-line?
