I was using `printfmtln` from `Formatting.jl`. Now I want to change my code to use `MicroLogging.jl`. Is there a neat way to do it?  
I need something like this

```julia
printfmtln("{:2d}) Loss={:.6f} |β|={:.2f}", iter, loss(β), sum(abs.(β)))

```

to be

```julia
@debug format("{:2d}) Loss={:.6f} |β|={:.2f}", iter, loss(β), sum(abs.(β)))

```

How about:  
`@debug f"\%2d(iter)) Loss=\%.2f(loss(β)) |β|=\%.2f(sum(abs.(β)))"`

If you like that, do `Pkg.add("StringLiterals")` and then `using StringLiterals`.
