only happens if scan methods are called not via #next;

private-scanning
o  scanAnySymbol

o  scanBinary: aClass alreadyRead: prevCharacter
This doesn't parse according to the ANSI draft. It only parses 1 or 2 letter binary tokens.

o  scanByteArray

o  scanExponentMultipler
Did not read a valid exponent, e must be start of a message send

o  scanExtendedLiterals

o  scanExtendedSymbol
scan symbols like #. which are allowed by Squeak and ST/X but aren't standard

o  scanIdentifierOrKeyword
:

o  scanLiteralArray

o  scanLiteralCharacter
$

o  scanLiteralString

o  scanLiteralString: class

o  scanLiteralString: class recurse: recurse
cg: qho calls this, ever?

o  scanName
scan over alphanumeric characters.

o  scanNamespaceName

o  scanNumber
sets tokenNumberBase as side effect.

o  scanNumberIBM

o  scanNumberOfBase: anInteger
Scan a number. Return the number or nil if the current input isn't a valid number.

o  scanNumberVisualWorks

o  scanNumberWithoutExponent
Scan an IBM number with the radix -- don't scan the exponent though

o  scanOldStyleAssignOrIdentifier
invoked when an underscore is encountered

o  scanPatternVariable
ST/X new: `' makes it a regex-string '

o  scanQualifier

o  scanSTXPrimitiveCode
scan an inline C-primitive; % { has already been read.

o  scanSpecialCharacter

o  scanStringSymbol

o  stripCommentInto: whichCommentCollection
an EOL comment; stop is the char pos BEFORE the cr

o  stripSeparators

o  stripSeparatorsAndCommentsInto: whichCommentCollection

scanning
o  next
The EOF token should occur after the end of input

o  scanBinary: tokenClass
in '-<digit>', the '-' is scanned as a sign;

o  scanLiteral

o  scanLiteralArrayParts

o  scanSymbol
Squeak symbols may begin with a colon

o  scanToken
fast-n-ugly. Don't write stuff like this. Has been found to cause cancer in laboratory rats. Basically a
case statement. Didn't use Dictionary because lookup is pretty slow.
