RE: Support for operator overloading

Hello,
Would you like the over loading to be scoped? What about allowing you to
alias a syntax symbol to a method call. Something like (each pair
exclusive syntax form):

// array1 + array2
Alias infix + MyArray.combine(#1, #2);
Alias : mapin #1 + #2 : mapout MyArray.combine(#1, #2);

// % s1 s2 s3
Alias postfix : start % : count 3
StringBuffer.append(#1).append(#2).append(#3);
Alias : mapin % #1 #2 #3 : mapout
StringBuffer.append(#1).append(#2).append(#3);

// MyArray[key1]
Alias wrap : start [ : end ] : inner 1 #1.getValue(#2);
Alias : mapin #1[#2] : mapout #1.getValue(#2);

// MyArray[key1]= value1
Alias wrap : start [ : end ]= : inner 1 : outer 1 MyArray.setValue(#1,
#2);
Alias : mapin #1[#2]= #3 : mapout #1.setValue(#2, #3);

Should the alias only take affect if the objects match the signature and
arguement type? Is it time that we move towards having a clean and
simple macro system? Those who would want more sugar can have it at any
time. And if some syntax is a fad, it just won't be adopted by the
community.

Subject: [Beanshell-dev] Support for operator overloading

Hi all,

Does anybody know if there has been any work, or plan, to make Beanshell
support operator overloading?

Because i was thinking about adding that support (would be very useful
for this project i'm working on), but i don't want to reinvent the
wheel.

Cheers,
J.V.
