using a (item () of ()) list block in other blocks that expect number values; the code can be optimized

[52525rr]

this compiles to

((+(b0.value[1 - 1] ?? "") || 0) + 0)

but since undefined is a falsy value this could be optimized to

((+b0.value[1 - 1] || 0) + 0)

this can also be applied for list indexing where the compiler knows the index should be a number.

generates

((+(b0.value[(((+b1.value || 0) + 0) | 0) - 1] ?? "") || 0) + 0)

but similarly can be optimized to

((+b0.value[(((+b1.value || 0) + 0) | 0) - 1]  || 0) + 0) 

for list indexing where the compiler doesnt know that the index is a number, perhaps another version of listGet is created that doesnt do the nullish check.
