SVM - custom kernels

Currently, after setting kernel_func it is immediately transformed into an instance of KernelFunc and getting the original kernel object or its attributes is impossible.

import Orange
svm = Orange.classification.svm.SVMLearner()
svm.kernel_type = svm.Custom
mykernel = lambda i1, i2: 0
mykernel.gamma = 1
svm.kernel_func = mykernel
svm.kernel_func.gamma # does not work

It would be useful to be able to access the kernel object (to see which one it is, see its parameters, ...).
