Thanks for sharing :)

Right. 

At first glance, it doesn't seem to mimic the file:read (···) API though, even the 5.1, as it seems to ignore all the varargs, excepts the first one.

For example:

print( vio.open( 'foobar' ):read( 3, 3 ) )

> foo

I would expect 'foo' and 'bar', considering that there are two formats specified.

Ah, and, yes, it also drops the last empty line:

local aString =
[[

foo

bar

baz

]]

local aCount = 0

for aLine in vio.open( aString ):lines() do
  aCount = aCount + 1
  print( aCount, aLine )
end
