One of the things I like about languages like Java is that since it is
statically typed I get tools that assist me when I write code, for
example if I misspell a function name.

What I really hate about dynamic languages is that, for example in
JavaScript if I misspell something there is no tool to find it and no
(deterministic) test locate this bug. I could actually deploy and find
the mispelled name only when I get its use case.

Does the fact that Ruby is STRONG dynaically typed, assist tool
developers? Can I have tools with minimal analysis capabilities?
