G'day
I just had a quick look into the past and saw a discussion in late 2009 about pass by reference. Has the situation changed at all? Reason I ask regards the RosettaCode question 'Generic Swap'; an Euphoria solution would seem to require pass by reference (or else something uniquely Euphorian that I'm ignorant of.)
Currently Euphoria can't do a generic swap.
I expect that either pass-by-reference and/or a swap operator will be implemented for Euphoria before too long.
I did start to do a swap operator but due to time constraints with getting v4.0 "out the door", work was suspended on it. I got it working in the interpreter and partly working in the translator. It would look like this ...
a <=> b
where 'a' and 'b' can be any Euphoria data type and the data types of 'a' and 'b' were compatible with each other.
