Examples

pigIt('Pig latin is cool'); // igPay atinlay siay oolcay
pigIt('Hello world !');     // elloHay orldway !

pigIt(@"Pig latin is cool"); // => @"igPay atinlay siay oolcay"
pigIt(@"Hello world !");     // => @"elloHay orldway !"

pig_it('Pig latin is cool') # igPay atinlay siay oolcay
pig_it('Hello world !')     # elloHay orldway !

pig_it('Pig latin is cool') # igPay atinlay siay oolcay
pig_it('Hello world !')     # elloHay orldway !

Kata.PigIt("Pig latin is cool"); // igPay atinlay siay oolcay
Kata.PigIt("Hello world !");     // elloHay orldway !

pig_it("Pig latin is cool");   // igPay atinlay siay oolcay
pig_it("Hello world !");       // elloHay orldway

PigLatin.pigIt('Pig latin is cool'); // igPay atinlay siay oolcay
PigLatin.pigIt('Hello world !');     // elloHay orldway !

(piglatin/pig-it "Pig latin is cool") ; "igPay atinlay siay oolcay"
(piglatin/pig-it "Hello world !")     ; "elloHay orldway !"

pigIt('Pig latin is cool'); // igPay atinlay siay oolcay
pigIt('Hello world !');     // elloHay orldway !

      PigIt str = 'Pig latin is cool' => result = 'igPay atinlay siay oolcay'
      PigIt str = 'Hello world !'     => result = 'elloHay orldway !
