Hi,
  I have developed in visualworks 5i.4 from Cincom
Corporation,=
 another Smalltalk platform. Now I will develop some
applications=
 in Squeak, however, I find many basic methods
disappearing, such=
 as "matchesPattern: ignoreCase: do:". So I want to
know whether=
 this is deficient in Squeak, or there exist some
better methods=
 to replace the old ones. What is more,  if a new
method contains=
 unknown methods, which will be defined in the future,
then it=
 can not be accepted. I think it is not convinient for
developing=
 application.
