  But people use third party software for debugging, aka debuggers. 
luacheck is just a special type of debugger.  Heck, a lot of programmers use
IDEs and simply can't deal with using a normal text editor.  Is that a
crutch? [1]

  And yet, Lua doesn't warn me when I inadvertantly reassigned a variable
with a different type [2] and *that* error is just as nasty as a typo ...

[2]	That bit be recently.  I had [3]:

		local lpeg = require "lpeg"

		-- ...

		local seconds             = P"T"
		local remoteuser          = (modifier * P"u")
		                          / function() return Cg(e_atom,"ruser") end
		local url                 = P"U"
		local servername          = P"v"

		-- ...

		local pat = apache:match[[[[%h %l %u %t \"%r\" %>s %b \"%{Referer}i\" \"%{User-Agent}i\" %{outstream}n/%{instream}n (%{ratio}n%%)]]

		-- ...

			data = pat:match(log_entry)
			data['Referer'] = url:match(data['Referer'])
			-- oops!
