# Identifier operator number separator:
avnCXV += 5;

# Punctuation symbols.
!\$%\&\*\+\-/:\<=\>\?@\\\^_`\|

# Illegal characters.

# These character constants ought to (?!) confuse it:
''''\A/''"''\'
# That's the character constant ''' followed by the character constant '\A\' followed by the character constant '"', followed by a syntax error.

# Here are some constants, identifiers and keywords, with a few separators scattered around, and a literal string in the middle. The string contains a newline and a hash and an escape sequence:
Hello, there. How ARE you today? "GREAT,
#thanks\21/" I said.

# A number literal:
1F.3o0

# Constant, keyword, identifier:
A BB ccc

# Constant, keyword, separator, constant:
Anybody THERE? AAbBB6B

# Something with brackets nested to a depth of six:
PUBLIC STATIC VOID Main(String[] args) {
  for (int i=0; i<10; i++) {
    # Comment in the middle.
    if (you feel like it) {
      Process(
        ['0'-'9']['0'-'9''A'-'F']*
        (?:'.'['0'-'9''A'-'F']*)?
        (?:['b''q''o''d''h']'-'?['0'-'9']+)?
      );
    }
  }
}

# And another copy commented out:

#        (?:['b''q''o''d''h']'-'?['0'-'9']+)?

#Some numbers:
0F.55555555h0
44.
45
1b20
1d-6

# Some non-numbers. They all contain numbers, but all contain something else as well. The first starts with a constant and a separator. The second starts with a separator. The third, fourth, fifth and sixth are truncated. The sixth ends with a constant:
F0.55555555h0
.44
0F
1b
1b-
1b-A

# Some expressions with lots of constants, identifiers, operators and numbers and the odd bracket (which counts as a separator for syntax colouring) and keyword:
