When should you prefer basic regex syntax, and when should you avoid it?

When working with regular expressions in Perl, it's essential to know when to use basic regex syntax and when to opt for more advanced features. Basic regex syntax is suitable for straightforward pattern matching and is generally more readable, making it easier to understand for those who may not be familiar with more complex constructs.

However, when dealing with complicated string manipulations or when performance is crucial, you should consider avoiding basic regex syntax. In such cases, advanced regex features like lookaheads, lookbehinds, and non-greedy qualifiers can significantly enhance your matching capabilities and improve efficiency.
