I second this. I'm not sure that syntax would be best but some sort of
/explicit/ syntax to make an expression into a delegate (a /shorthand/
for the {return exp;}, not another "convention") would be much less
confusing.
options: (Just off the top of my head)
op Expression
op ( Expression )
op == one of: "&", "@", "^", "$", "\"
The &(exp) form looks interesting:
"take the address of this R-value".
Kinda sounds right. Have to think on that.
