Re^3: Fast Way to Split String in to Chunk of Equal Length

[BrowserUk]

At it again. Unannounced updates. The above post originally consisted entirely of just:

Any implementation in mind? Something like the following?

while ($seq =~ /(.{3})/sg) {
   # Substring in $1
   ...
}

To answer the dumb question that wasn't there originally,

How can you not know in advance how many fields there are (int(length($seq)/3))?

If you have to calculate the number, you throw away the few percent gained.
