Programtic creation of variables from python

[glenfletcher]

After scanning through the code I'm not certain that this feature doesn't already exist, If it dose it obscure and undocumented, however I don't think its actually been implemented.

If its all ready possible to do this how to do so should be documented.

As for what I think this feature should be it the ability to pass a dict of less variables to the compile function, along with python functions for creating and manipulating these variables, some of these functions do exist, but they appear to be undocumented internal functions for handling the equivalent functions calls in the less code it self.

current compile sig:
def compile(file, minify=False, xminify=False, tabs=False, spaces=True):

suggested sig:
def compile(file, minify=False, xminify=False, tabs=False, spaces=True, variables={}):

suggested ussage:

compile(path_to_compile, variables={
  'bg-color': colors.rgb(50,60,120),
  'fg-color': colors.hsl(90, 75, 40),
  'banner-image': image_url
})

This would provide for the usage of less as a template system for CSS with dynamic content generations, for example a CMS with several parameters for defining the sites colour scheme.
