Dynamic typing just relax you at coding and compiling moment. The type
interferacing is done at runtime.
The pro is less formal coding especially on algorithms and cons that
data structures must be documented outside the code unless language
supports type specifing.
Just read about haskell it will give you the wisdom (google "learn
haskell for great good"), for example haskell is static typed but it
also gives you power of algorithm eloquence like you would write in
dynamic language, just at some point in code you must specify what
types you are actually using in your solution.
