So I took a look at the fish documentation and it said:"*temporarily
block delivery of events*".
The synopsis said:
/*block [(--local | --global)]*//*
*//*block --erase
*/According to this it can be used without any arguments or parameters.
Yeah, the man page is surprisingly nondescript about the default behavior.
From the source code, it looks like block defaults to the nearest
function scope. So, if you invoke it w/in a "syntax block" (like an if
statement, e.g.), it will scope itself to the nearest function "syntax
block."

I would guess this is for convenience in scripts. Block would typically
be used in a function, so it makes sense to default limit it to the
scope of that function.
