So the problem seems to be that if shell parses the script before we
define aliases they are not expanded in the code shell already parsed.


This works:

alias tst_res="..."

tst_res TINFO "foo"


This does not:

tst_res TINFO "foo"

alias tst_res="..."

The tst_loader.sh has to be sourced first after all.
