two ideas: (not that i have done anything similar)

1: parse a user string with the whole expression to build the operating objects:

m=import "matrix"
m.var("A") = {.... data...}
m.var("B") = {....more data...}
for n=1,1000 do
   m.oper ("A = A * B")
end
print (m.get("A"))


2: override operators in your userdata; but don't make them calculate,
make them generate the calculators, a bit like LPEG constructing
operators
