Too Many `a`s (with apologies to Dr Seuss)

	(Original here http://www.poetryfoundation.org/poem/171612)
	Did I ever tell you that Programmer McCave
	Had twenty-three variables and he named them all `a`
	Well, he did. And that wasn't a smart thing to do.
	You see, when he wants wants to add `a` to 2
	He doesn't get a number oh no no no
	All twenty-three `a`s cause a buffer overflow
	This makes things quite difficult at the McCaves'
	As you can imagine, with so many `a`s.
	And often he wishes that, while he was coding,
	He hadn't ignored that sense of foreboding
	And called one of them runCount, And one of them lastNum
	And one of them allSales and another roundSum
	And one of them lastId, and another userNames
	And one subnetMask, or numStartedGames
	Any old names would actually do
	even if they were just `bar` or `foo`
	And adding hyphens or humble underscores
	He could have come up with so many more!
	Like read_app_config_from_this_file_name
	But no, he went and called them all the same
	If only he hadn't given into the hype
	And used a language strongly typed
	He would have avoided this horrible fate
	But he didn't and so now it's too late.
