Christian has covered all the points I was going to look for, but I was
going to suggest that if you get something like fannkuch running we can
make some general comparisons. Smalltalk and Ruby have similar properties
that mean they probably look pretty similar in their ASTs, such as closures
for control structures and operators being method calls, so I can relate
what I know about using Truffle for those kinds of problems to Smalltalk.
