Generate a random alphanumeric string.

The argument n specifies the length, in characters, of the alphanumeric string to be generated. The argument chars specifies the character list which the result is consist of.

If n is not specified or is nil, 16 is assumed. It may be larger in the future.

The result may contain A-Z, a-z and 0-9, unless chars is specified.

require 'random/formatter'

Random.alphanumeric     #=> "2BuBuLf3WfSKyQbR"
# or
prng = Random.new
prng.alphanumeric(10) #=> "i6K93NdqiH"

Random.alphanumeric(4, chars: [*"0".."9"]) #=> "2952"
# or
prng = Random.new
prng.alphanumeric(10, chars: [*"!".."/"]) #=> ",.,++%/''."

When there is an invalid block with a keyword missing an end right before another end, it is unclear where which keyword is missing the end

Take this example:

class Dog       # 1
  def bark      # 2
    puts "woof" # 3
end             # 4

However due to github.com/ruby/syntax_suggest/issues/32 the problem line will be identified as:

> class Dog       # 1

Because lines 2, 3, and 4 are technically valid code and are expanded first, deemed valid, and hidden. We need to un-hide the matching end line 4. Also work backwards and if there’s a mis-matched keyword, show it too
