How can I write my own decorator using xlwings decorators to create Excel UDFs - xlwings

Question

I would like to write my own decorator to create UDFs in Excel using xlwings decorator. However, when I import my function, the function name imported is the decorator inner function name's.
A dummy example to clarify:
import pandas as pd
import numpy as np
import xlwings as xw
def to_excel(f): # my decorator
#xw.func
#xw.arg('xl_app', vba='Application')
def wrapped(xl_app, arg1 =None, arg2 =None):
# do some stuff
return len(f(arg1, arg2))
return wrapped
def foo(dim1, dim2):
dim1, dim2 =int(dim1), int(dim2)
return pd.DataFrame(np.ones((dim1, dim2)))
#to_excel
def xlFoo(*args, **kwargs): # Excel UDF
return foo(*args, **kwargs)
If I import it into Excel, it will auto generate the below VBA code:
'Autogenerated code by xlwings - changes will be lost with next import!
Function wrapped(Optional arg1, Optional arg2)
If TypeOf Application.Caller Is Range Then On Error GoTo failed
wrapped = Py.CallUDF("xl2", "wrapped", Array(Application, arg1, arg2), ThisWorkbook, Application.Caller)
Exit Function
failed:
wrapped = Err.Description
End Function
If I replace wrapped by xlFoo, it now works as expected:
Function xlFoo(Optional arg1, Optional arg2)
If TypeOf Application.Caller Is Range Then On Error GoTo failed
xlFoo = Py.CallUDF("xl2", "xlFoo", Array(Application, arg1, arg2), ThisWorkbook, Application.Caller)
Exit Function
failed:
xlFoo = Err.Description
End Function
