Re: -> operator

in reply to -> operator

There are disambiguation rules, for example:

If the -> is followed by braces or brackets, it's a hash or array lookup
Otherwise, if the LHS is a blessed reference, it's dispatched as a method call
If the LHS is a package name, the RHS is interpreted as a sub and the first arg is the LHS (this is quasi identical to the previous case).

I'm sure there are more rules, but in general it does what I mean (dwim) ;-)

I think the word "method" is better than "sub" there, as method dispatch occurs in this case. (Use B::Concise and look for an op named `fetchmethod` or something similar.)	[reply] [d/l]
