This will cause decorated functions to be run using the psyco optimizer. It will allow the code to continue working even if psyco is not available

Decorator:

try:
    import psyco
except:
    pass

def optimize(func):
    try:
        return psyco.proxy(func)
    except:
        return func

Usage:

@optimize
def complex_function(n):
    ... do complex stuff with n ...
