//I feel it might be difficult. Define the following:
//
// "abc\n".split("\n").join("\n")
I thought we can cater that w a limit parameter,
irb(main):040:0> "\nabc\ndef\n".split("\n",-1).join("\n")
=> "\nabc\ndef\n"
and that split by itself (w/o limit param) simplifies by trimming trailing
edges -which is good in some cases, imho.
My remainng concern is [] vs [""] thingy. Both behave similarly w split and
joins, yet I prefer the [""]. But that is just me.
irb(main):046:0> "a".split("b")
=> ["a"]
irb(main):047:0> "".split("b")
=> [] #<=== I was hoping for [""] here
No worry here, this just very small concern.
irb(main):065:0> [""].collect{|x| x+"!"}
=>["!"]
irb(main):066:0> [].collect{|x| x+"!"}
=>[] #<== [] acts like blackhole
