print "Hello" .. "world!";

Concat on raw strings is a good candidate.

Snipping out Toy_AstGroup when encountered.

Compute literal value expressions (like, 3*5 would be 15 in the bytecode, etc.).

Removed optimizations in ca4073a.

[Ratstail91]

References may be a thing down the line - could they be replaced with direct usage at thr bytecode level?

[Ratstail91]

From #133

Duplicate strings in bytecode.

[Ratstail91]

Removing the assertion checks, see #145 .

Done, and controlled via a command line switch to the repl.

[Ratstail91]

Removing scope-pushes in single-line blocks?

if (x) {
    print "foo";
}

In this case, pushing and popping a scope isn't needed. If something is declared, then you'd still need a scope.

[Ratstail91]

if (false) will never be true.

[Ratstail91]

likewise, if (true) won't allow the else branch to run.

[Ratstail91]

while (true) runs forever, and while(false) could be snipped out.
