GLU/SwiGLU 在实际中是门控形式（two linear branches），是向量上的逐元素操作；为了在一维上可视化，我用简化的标量形式来画图 —— 把两条分支都用相同的输入值（即把 a=x, b=x），因此 GLU(x)=x∗sigmoid(x) SwiGLU(x)=x∗SiLU(x) 。这能直观展示门控机制的形状差异。

With normal Smalltalk code, I would explore the system using senders, implementors, inspectors— gradually rebuilding my understanding. Here, that breaks down. The matching syntax lives inside strings, invisible to standard navigation tools. No code completion. No refactorings. No help from the environment.
that we can do it in user-space effectively gives us two stacks (one that we
