"What is the point of glue languages" indeed. Loading parameters into a program makes sense for a scripting language, especially for interacting with code you didn't write. But when 99% of your problem is solved with custom-made C/C++/whatever (as is the case with simulations), the value-add of a glue language is very little. Professionally, I've written trading simulations in C++ where Python was used for glue code. It added very little value and added more dependencies/headaches. Julia could've have replaced both.
