Trafaret object to pass value as is

[ant5]

Hello and thank you for your work fiirst of all.

I have a small suggestion to use trafaret in more uniform way. I have some data with assigned trafaret and some without constraints. So I have to do something like this:
if data.trafaret:
val = data.trafaret.check_and_return(rawval)
else:
val = rawval

If you'll kindly add an object something like "NoCheck" which will pass arguments out without any check it will be possible to always do:
val = data.trafaret.check_and_return(rawval)

while data without constraints will be initialized as:
data.trafaret = trafaret.NoCheck()

can You try trafaret.Type(object) ?

try trafaret.Any

We probably have not the best docs, so will not close this now and will treat it as doc issue.

I've tried trafaret.Any(). But it seems no luck:

import trafaret
tft = trafaret.Any()
tft.check_and_return('aaa')
Traceback (most recent call last):
File "", line 1, in
AttributeError: 'Any' object has no attribute 'check_and_return'

[Deepwalker]

check_and_return, check_value, transform is internal methods for trafarets. Use just direct call (value) or check(value). Trafarets are callables.

Oh, I see. Thanks all. Also thank you for point me that trafaret is callable.
Both solution works:
import trafaret
tft = trafaret.Any()
tft('aaa')
'aaa'
tft2 = trafaret.Type(object)

tft2('aaa')
'aaa'

I prefer trafaret.Any() for readability.

Thank you again. I enjoy to produce really beautifull code with this library.
