Re^2: Regex being stupid

[Grimy]

While it is true that @( is a valid variable name, it doesn’t interpolate:

@( = (42, 12);  # valid statement
print "@(";     # doesn’t print '4212' but '@('
print '@(';     # same as above (obviously)

Thus, the @ in the regex doesn’t need escaping, strictly speaking. I’d still recommend escaping it, for clarity and maintainability.
