[Truffle] Adding progress on Array#[]=.

[bjfish]

I’ll be working on getting more of these specs passing.

This caused at least one failure (benchmarks still running), in fannkuch-redux.

You can test this locally by doing jt debug classic-fannkuch-redux. Can you take a look?

[bjfish]

@chrisseaton yeah i can take a look

[bjfish]

@chrisseaton happen to know how to resolve this bench error?

[chrisseaton]

Is this still a problem? I saw the PR to fix fannkuch.

[bjfish]

@chrisseaton I fixed fannkuch but never got jt bench debug classic-fannkuch-redux command to work. I'll take a look at running this command later on.
