There are four possible forms of parsed output. Typing on
FriCAS command line:
)boot $RawParseOnly := true
cause FriCAS instead of compiling to print raw parse tree
(that is directly output from the parser).
)boot $FlatParseOnly := true
prints somewhat flattened version of parse tree (bigger
parse trees should be more readable, but otherwise this
form is not used)
)boot $PostTranOnly := true
prints parse tree after first auxiliary transformation
)boot $PrintOnly := true
prints parse tree after second auxiliary transformation.
This form is used by Spad compiler.

It is interesting project. Difficulty depends largely on how
well Spad concepts map to Julia. IIUC core ideas of Julia
are quite similar to Spad, so it looks possible.
