描述

I'm running into what may be a conceptual issue rather than an actual issue. Are multi-character match variables supported?

E.g.

let string = "test"; match(string)( (s) => { console.log(s); } )

Executes as expected logging

test

but

let string = "test"; match(string)( (str) => { console.log(str); } )

generates no output.

研究方向
The issue describes a bug where the match function fails to execute when the variable name in the matcher has more than one character (e.g., 'str' vs 's'). To reproduce, use a multi character variable name in the match callback; single character names work. The root cause likely lies in the pattern matching parser or the way variables are extracted from function parameters. Investigate the source code, particularly the match function implementation and any regex or string manipulation that might be limited to single characters. Since the issue is from 2020, first verify if the bug still exists in the current version by testing locally or checking recent commits. If confirmed, a fix would involve adjusting the parameter extraction logic to support multi character variable names.
