haven't head anyone recently advocating for TLpSi. You can achieve
almost the same thing using SQ by wrapping a block around each
script body.
Right, although TLpSi is still attractive as a parallel to function
bodies, where we agreed body-level let has to bind in a body block
that shadows parameters and vars. Not much of a plus but it's a
plausible alternative.
did you just say that this is legal:
function f() {
var b;
let b;
}
and interpreted as:
function f() {
var b;
{ let b; }
}
I didn't say that. Your

has two alternative rules, either way var vs. let at top level for a
given name is an error.
Of course, I *did* say "shadows ... vars" but I was thinking of
parameters. Andreas in followups in the thread cited above argued that
such let vs. arg shadowing might be ok, it was a minor point.
To your point, I think we did agree at the meeting with making let vs.
arg as well as let vs. var an error.
