regex - Formal language expressiveness of Perl patterns -

शास्त्रीय नियमित अभिव्यक्ति परिमित automata के बराबर हैं। "नियमित अभिव्यक्ति" के अधिकांश वर्तमान कार्यान्वयन कड़ाई से नियमित अभिव्यक्ति नहीं बोल रहे हैं लेकिन अधिक शक्तिशाली हैं। कुछ लोगों ने "नियमित अभिव्यक्ति" की बजाय "अधिक सटीक" शब्द की बजाय "पैटर्न" शब्द का उपयोग करना शुरू कर दिया है।

एक आधुनिक "नियमित अभिव्यक्ति" जैसे कि पैटर्न 5 पर्ल में समर्थित?

अपडेट: "पर्ल 5" का मतलब मेरा मतलब है कि पर्ल 5 में लागू की गई पैटर्न मिलान की कार्यक्षमता और कई अन्य भाषाओं (सी #, जावास्क्रिप्ट, आदि) द्वारा अपनाई गई थी और पर्ल के लिए कुछ विशिष्ट नहीं है उदाहरण के लिए, मैं एक पैरामीटर में पर्ल कोड को एम्बेड करने के लिए ट्रिक्स पर विचार नहीं करना चाहता।
