[myhdl-list] Function calls in combinatorial blocks

[Per K. <bas...@gm...>]

Hi!
Is there a particular reason that we do not support function calls in
combinatorial blocks?

In 0.7 I get:
  File "[...]_analyze.py", line 165, in _analyzeGens
    _isMem(obj) or _isTupleOfInts(obj)

In 0.8dev I get:
  File "[...]_analyze.py", line 168, in _analyzeGens
    raise ConversionError(_error.UnsupportedType, n, info)
myhdl.ConversionError: File file.py, line 11: Object type is not supported
in this context: f

Here is a test snippet:
#########################
from myhdl import *

def w(a, b, c, clk):
    def f(a):
        out = intbv(0)[len(a):]
        if a<3:
            out[:] = a
        else:
            out[:] = 0
        return out

    @always_comb
    def cm():
        b.next = a

    @always(clk.posedge)
    def ck():
        c.next = f(a)

    return instances()

def test():
    a = Signal(intbv(0)[10:])
    b = Signal(intbv(0)[10:])
    c = Signal(intbv(0)[10:])
    clk = Signal(bool(0))
    dut = toVerilog(w, a, b,c ,clk)
    return instances()

s = Simulation(test())
s.run()
