描述

A cell in pluto:

begin
    local function f(x)
        x^3
    end
    f(2)
end

This runs as expected and f is not available outside the begin-block, but if another cell also defines local function f(), I still get a Multiple definitions for f error.

研究方向
The issue involves Pluto's scoping mechanism for local functions across cells. Look into the source files related to variable scope analysis, likely in `src/analysis/Scoping.jl` or similar. Understanding how Pluto currently detects multiple definitions and why `local function` avoids the first pass check but still triggers the error is key. Consider exploring the notebook's execution model and cell isolation to propose a fix.
