 it has nothing to do with const_get, remove the line

   ARGV.each { |c| dynamic << Kernel.const_get(c).new }

 and you'll see that you have the same error


R>                 puts gets
                        ^^^^

 the problem is here

svg% ri Kernel::gets
----------------------------------------------------------- Kernel::gets
     gets( aString=$/ ) -> aString or nil
------------------------------------------------------------------------
     Returns (and assigns to $_) the next line from the list of files in
                                               ^^^^^^^^^^^^^^^^^^^^^^^^^
     ARGV (or $*), or from standard input if no files are present on the
     ^^^^
     command line. Returns nil at end of file. The optional argument
     specifies the record separator. The separator is included with the
     contents of each record. A separator of nil reads the entire
     contents, and a zero-length separator reads the input one paragraph
     at a time, where paragraphs are divided by two consecutive
     newlines. If multiple filenames are present in ARGV, gets(nil) will
     read the contents one file at a time.
        ARGV << "testfile"
        print while gets
     produces:
        This is line one
        This is line two
        This is line three
        And so on...

svg% 

 If you give it arguments, it will try to read from these files

 You want IO#gets rather than Kernel::gets
