A good high level goal to "finish" the WASM effort is to take some code like Minpack or equivalent and get it compiling via WASM and get it working via wasmtime as well as in the browser.

We can do a progression of programs:

[ ] examples/expr2.f90
[ ] something intermediate (LPython or LFortran)
[ ] Minpack

For all these, the following should work:

lfortran --backend=wasm examples/expr2.f90 -o expr2.wasm and wasmtime expr2.wasm as well as running in the browser
lfortran --backend=wasm_x64 examples/expr2.f90 -o expr2
