Thanks, I'd appreciate a lot.
I'll merge this with a small change tomorrow(about the trailing space).

Thanks again for the impressive notes about expression problem.
I'd like to add it to documentations.

Besides, your git config seems broken, so that you were not recorded at https://github.com/thautwarm/MLStyle.jl/graphs/contributors.
I'd recommend you to set email via git config (--global) user.email xxx@xxx.

To add you to the contributors, I'm to fix the git tree because I don't want to
loss a conscientious contributor.
