some examples from documentation do not run out of the box on Python 3.4

Migrated issue, originally created by Matthis Thorade (@thorade)

Warning: I am a Python and Mako newbie, so I might be missing something obvious.
I downloaded WinPython 64bit 3.4.2.3 and installed Mako using pip.
The first example from the Mako homepage

from mako.template import Template
print Template("hello ${data}!").render(data="world")

did not work for me.
To make it work, I had to put parantheses around the print part, like this:

from mako.template import Template
print(Template("hello ${data}!").render(data="world"))

Maybe you want to adapt that example on the homepage and in the documentation, to save some unexperienced people some time.

OK, this might be Python 2 versus Python 3. Just guessing.
Second example also has to be adapted to make it work with Python 3:

from mako.template import Template
from mako.runtime import Context
from io import StringIO

mytemplate = Template("hello, ${name}!")
buf = StringIO()
ctx = Context(buf, name="jack")
mytemplate.render_context(ctx)
print(buf.getvalue())

Two lines changed: io instead of StringIO and parantheses for print

oh just the homepage? nothing in the docs themselves?

The example on http://www.makotemplates.org/ needs to be changed to

from mako.template import Template
print(Template("hello ${data}!").render(data="world"))

I'll work my way through the documentation in the next days, make a list and possibly send a pull request afterwards.
Using print() instead of print should not break Python 2.7 compatibility, so I'll change that.
The other example (io versus StringIO) is more difficult to handle.

Closing this for now, if I happen to see any example that does not work on Py3 I'll reopen or send a PR.
