ok, here's example code for it:

from textwrap import dedent

class dedentify(object):
    def __init__ (self, f):
        self.f = f
        
    def __call__ (self, message):
        self.f(dedent(message))

@dedentify
def warn (message):
	print (message)

warn("""\
            Hello dear sir,
            I am sorry to inform you
            the spanish inquisition
            has arrived""")

now prints:
Hello dear sir,
I am sorry to inform you
the spanish inquisition
has arrived

I hope this is what you had in mind ?
