Allow interpolating in LHS of the rules #275

Closed shashi closed 3 years ago

shashi commented 3 years ago

Came up while matching this:

using ModelingToolkit
@parameters x t
@variables u(..)
Dx = Differential(x)
rhs = Dx(u(t, x))
r = @rule Differential(x)(u(t,x)) => "yes"
@show r(rhs.val) # nothing

But now you can do

r = @rule $(Differential(x))(u(t,x)) => "yes"

and it will match
