ruby - What is a def ... else ... end construct? -

i have code:

def with_else puts 'we come in funny' if true puts "yes" 'return yes' end 'return what?' else puts 'no' 'return else -> no' end puts with_else

and output this:

we come in funny yes no homecoming else -> no

why don't error that? def/else/end mean?

this part of larger syntactical structure:

def foo # method stuff rescue # stuff if exception caught else # stuff if no exception caught ensure # run after rescue , else end

but each section optional! can leave out rescue , ensure example.
