Description
With pn.bind you can provide constants as arguments. In the documentation it says that pn.depends is the annotator equivalent of pn.bind. But that is not fully true as you can provide constants as arguments to pn.bind but not to pn.depends.
This difference is friction as some users might stumble here and it also makes it more time consuming to refactor from a pn.bind to a pn.depends implementation and vice versa.
pn.depend does not work
import panel as pn
widget = pn.widgets.IntSlider(value=1, start=1, end=5)
@pn.depends(a=widget, b=1)
def add(a,b):
return a+b
pn.Column(widget, add).servable()
pn.bind works
import panel as pn
def add(a,b):
return a+b
widget = pn.widgets.IntSlider(value=1, start=1, end=5)
add=pn.bind(add, a=widget, b=1)
pn.Column(widget, add).servable()
