Comment (by rws):
Isn't this a bug? Hold as no effect:
{{{
sage: from sage.symbolic.function import BuiltinFunction
sage: class MyFunction(BuiltinFunction):
....: def __init__(self, name):
....: BuiltinFunction.__init__(self, name, nargs=1)
....: def _evalf_(self, x, parent=None, algorithm=None):
....: print algorithm
....: return x
sage: f = MyFunction('f')
sage: ex = f(0.0, algorithm='algoA', hold=True); ex
algoA
0.000000000000000
sage: sin(0.0, hold=True)
sin(0.000000000000000)
}}}
