i think what Tim answered is correct. but, i believe the "desired"
approach is to put all those blocks to be tangled to the same file under
a headline with a property drawer containing something like:
----
:header-args+: :tangle "submsim.jl"
----
i believe this is for performance of tangling, but possibly the
"multiple source blocks to same :tangle'd file" feature may disappear?
cheers, Greg
