A History of Regular Expressions and Artificial Intelligence. I have an unusually good memory, especially for symbols, words, and text, but since I don’t use regular expressions (ahem) regularly, they ...

Thompson's Construction Algorithm is used to build NFA's from the user's input in postfix notation. Both NFA's and Regular expressions have the same computational power, therefore any language that ...

After reading I became curious as to why Perl and other languages features regular expression don't use the Thompson NFA approach. Can someone out there enlighten me? Thank you kindly.
