in thread Find element in array

Take a look at that warning message:

Sequence 'TAAGAACAATAAUAACAA' in line 2 has invalid character after 12 + at line 7, <DATA> line 2. ^^^^^^ + ^^^^^^

The warn function already includes $. in its output, unless your message ends in "\n".

    I've been aware of this, but how can we know if the OP will use warn for logging or doesn't prefer to push the line-numbers in an array?
