I’m trying to use the @load macro from MLJ.jl, which looks like this:

```julia
classifier = @load AdaBoostClassifier

```

I want to loop through multiple arguments, so I’d like to do something like

```julia
cname = "AdaBoostClassifier"
classifier = @load $cname

```

but as this is a macro, the string isn’t interpolated into the macro. Past posts talk about putting string interpolation into macro definitions, but I just want to use an already-provided macro.

I’d say the easiest route is to use `load` (i.e. `MLJ.load(cname)`) see also `?MLJ.load`
