Method definition *(Number, SciMLBase.AbstractDiffEqLinearOperator{T}) overwritten in module DiffEqOperators

[oashour]

I'm using DifferentialEquations.jl and DiffEqOperators.jl in my package (Julia 1.5.2). Recently this error started popping up when precompiling my package.

WARNING: Method definition *(Number, SciMLBase.AbstractDiffEqLinearOperator{T}) where {T} in module SciMLBase at /Users/ashour/.julia/packages/SciMLBase/HlKbQ/src/operators/common_defaults.jl:15 overwritten in module DiffEqOperators at /Users/ashour/.julia/packages/DiffEqOperators/viN6A/src/composite_operators.jl:20.
  ** incremental compilation may be fatally broken for this module **

I am not sure if I'm doing something wrong in my package or what's up, I'm relatively new to Julia. The packages installed are:

Project NonlinearSchrodinger v0.0.5
Status `~/.julia/dev/NLSS/Project.toml`
  [a93c6f00] DataFrames v0.22.5
  [9fdde737] DiffEqOperators v4.21.0             <====
  [0c46a032] DifferentialEquations v6.16.0   <====
  [b305315f] Elliptic v1.0.1

  [91a5bcdd] Plots v1.10.3
  [5d786b92] TerminalLoggers v0.1.3
  [56ddb016] Logging

I can't reproduce this at the REPL just by activating the environment and running using DifferentialEquations, DiffEqOperators

Any thoughts?

It's at least harmless. It looks like it was introduced in:

SciML/SciMLBase.jl@87f08cf

@YingboMa #330 it looks like this library engaged in a bit of type-piracy which caused it. Do you think we could drop the Number definition for now? Anything come to mind for it?

Thanks as always Chris, I'll just ignore it for now. Wish I was knowledgeable enough to help fix this :)
