pfl2str(pattern) expands pattern-form expressions, which have the form
[<expr><op><expr>]
to the corresponding string.
The value of <op> determines the operation to be performed.
pfl2gxp(pattern) expands pattern-form expressions into generators
that, when compiled and evaluated, produce the corresponding
string.
pfl2pwl(pattern) converts pattern-form expressions to Painter's
weaving language.
