Thanks @wds15! Will strike those out from the list then.

If this could be done without a lot of complications and it would open up the possibility to deduplicate a lot of code then I am for it. If its...

If I run it locally for the matrix_exp_multiply only (`python3 runTests.py test/expressions/ --only-function=matrix_exp_multiply`, I can see the following error: ``` Running main() from lib/benchmark_1.5.1/googletest/googletest/src/gtest_main.cc [==========] Running 3 tests from 3...

Will check tomorrow.

I am unable to replicate locally (even with clang++-6.0) on Ubuntu. My next guess would be that the instance runs out of memory compiling 15 tests in parallel or something...

Getting back to this finally. - For the GHA error with Windows tests, I think what we need to do is https://github.com/stan-dev/math/pull/2630 I would prefer closing https://github.com/stan-dev/math/issues/2489 and bumping the...

> I'm asking just in case, if that could provide an easier way to get compound speedup without explicitly defining all possible glm functions? Unfortunately not, this just replaces calls...

I think in this case, the easiest thing to do is just create utility UDFs and use them. With shadowing and overloading this is now pretty simple: ```stan functions {...

If we only do this for array[] int for basic arithmetic, that would be fine. Also not a ton of work.

I don't think so. The currently supported signatures are: ``` gp_dot_prod_cov(array[] real, real) => matrix gp_dot_prod_cov(array[] real, array[] real, real) => matrix gp_dot_prod_cov(array[] vector, real) => matrix gp_dot_prod_cov(array[] vector, array[]...
