Subject: When arg is a variable,  can the variable's name be displayed?

Hi,

For debugging purposes,  I'd like to write a routine to dump a variables
name and value, sort of like Object#inspect but different.  I'd like to
write:

def dumpv(var)
    $stdin.print var.name + ' = "' + v.to_s + "\"\n"
    $stdin.flush
end

v1 = 'abc'
dump(v1)    #  ==>  v1 = "abc"

v2 = 123
dump(v2 )    #  ==>  v2 = "123"

I recognize that this simple thing,  if it worked for strings and numbers,
probably wouldn't work for some more complex types,  but I'll worry about
that another day :-)

And I acknowledge this isn't the world's greatest debugging tool,  but it'll
help me develop some tool-writing skills in Ruby.

TIA,
Richard
