Macros dv and pdv eat the subsequent paranthesis argument
The physics package has the macros dv and pdv which are great but I have a small problem with them.
If an argument with parenthesis included right after them they eat the whole argument. If there is a space in between the argument everything works fine but I want to prevent this happening all together. I checked the documentation but couldn't find a solution. So an example would be
documentclass{article}
usepackage{physics}
begin{document}
[dv{x}{t}(y^2-5) qquad dv{x}{t} (y^2-5) qquad dv{x}{t} ]
end{document}
I want the output of the equation on the left to be the same as the middle one.

That's because dv (which is a shorthand for derivative) is defined as
DeclareDocumentCommandderivative{ s o m g d() }
{ % Total derivative
% s: star for flatfrac flat derivative
% o: optional n for nth derivative
% m: mandatory (x in df/dx)
% g: optional (f in df/dx)
% d: long-form d/dx(...)
Even if the optional g-type argument is given (as in your case) the command will scan further for an optional delimited d-type argument which is delimited by ( and ) (maybe not the best choice in a mathematical context). To circumvent this you don't really have a choice but to insert a space.
At the same time I'd like to note that the physics package does not really help me writing physics formulae and I'm usually much better off typing the stuff by hand using the amsmath macros.
