"round trip" error

[justin2004]

this is in the README.md:

>>> apl.eval("'2+2' py.Eval ⍬") # round trip
4

but when I run that:

>>> apl.eval('2+2' py.Eval ⍬)
  File "<stdin>", line 1
    apl.eval('2+2' py.Eval ⍬)
                   ^
SyntaxError: invalid syntax

although this works

>>> apl.eval('2+2')
4

is the README out of date?
