[Bioperl-l] split-like function

[Rob Edwards]

If you use split(/(n{50,})/i) [note the extra ()] the n{50,} will become 
extra elements in the array. You can then use length on each element of the 
array to find the position of each of the n{50,} and how long each one is. 

e.g. split /(1+)/, "0000111122111333" gives an array 0000, 1111, 22, 111, 333
