I guess this comes from the fact that do is also used for flow control, which means it doesn't fall under the "Looks like a function" rule. print "Hello" if(0) || 1; prints "Hello", because if is not a function.

This behaviour is actually documented for last and its kind:

It is also exempt from the looks-like-a-function rule, so last ("foo")."bar" will cause "bar" to be part of the argument to last.

Thanks a lot that makes things a bit clearer. :)

But could you explain how do FILE which does per definition an eval is more a flow control than just eval ?

update

Not to mention that flow control statements don't return values. (maybe with the exception of short circuiting expressions)

My answer starts by "I guess", so you have to take it for what it is. do FILE; is kinda like goto FILE; except it works. Like goto, do has two different meanings depending on the syntax, and the flow-control side means the keywords are not parsed like most other.

Edit: I'm not saying that do is always flow control, but that since it may be, the parser deals with it differently
