Short question! Is there a way to conditionally produce a warning without writing the `if-end` block? It would look like

```julia
@warn x < y "you should know that x is less than y"

```

similar to the way that `@assert` works.

You can use `&&` or `||` for this instead:

```julia
x < y && @warn "you should know that x is less than y"

```
