argument lists or for #directive argument lists. Returns a list of

name.
These defVals are always strings, so (argName, defVal=None) is safe even
with a case like (arg1, arg2=None, arg3=1234*2), which would be returned as

The filters are functions which may modify the expressions or raise
a ForbiddenExpression exception if the expression is not allowed. They
are defined in the compiler setting 'expressionFilterHooks'.
Some intended use cases:
- to implement 'restricted execution' safeguards in cases where you
can't trust the author of the template.
- to enforce style guidelines
filter call signature: (parser, expr, exprType, rawExpr=None, startPos=None)
- parser is the Cheetah parser
- expr is the expression to filter. In some cases the parser will have
already modified it from the original source code form. For example,
placeholders will have been translated into namemapper calls. If you
need to work with the original source, see rawExpr.
- exprType is the name of the directive, 'psp', or 'placeholder'. All
lowercase. @@TR: These will eventually be replaced with a set of
constants.
- rawExpr is the original source string that Cheetah parsed. This
might be None in some cases.
- startPos is the character position in the source string/file
where the parser started parsing the current expression.
@@TR: I realize this use of the term 'expression' is a bit wonky as many
of the 'expressions' are actually statements, but I haven't thought of
a better name yet. Suggestions?
