Add type coercion option to ARGV.getopts arguements.
I suggest a little new feature to lib/optparse.rb.
When I created CLI tool I defined option parser with
ARGV.getopts function like following.
ARGV.getopts('abc:', 'logopt, 'optwithval:val')
It was so easy and short to recognize what is declared as options, but I could't force a type of the values.
Maybe it looks unshapely, but I'd like to confirm the types like this:
ARGV.getopts('strval:(String)intval:(Integer)', 'logopt', 'optwithval:val(String)')
Normal OptParser has type coercion but extended function
ARGV.getopts has no feature like this.
This difference is trivial but inconvenient.
