Is it possible to calculate a limit of a piecewise function?

[Helge Gabert]

Doesn't work for me, either.

However, if you put in a default condition at the end, like

piecewise(x<1,1,x>1,0,9)

all limits get computed

from the left limit x ->1^-1 returns 1

from the right limit x ->1^1 returns 0

from both sides limit x -> 1^0 returns "unidirectional limits are distincts [sic]".
