Hi

I see how Class work with propierties, but i think have troubles example:

class Abc
{       int myprop;
void property(int newproperty) { myprop = newproperty; } // set'er
int property() { return myprop; }       // get'er
int property(int start) { return myprop+start; }      // how work this?
}


I like delphi way (more clean):

class Abc
{       int myprop;
void prop(int newproperty) { myprop = newproperty; } // set'er
int prop() { return myprop; }       // get'er
property mypropety2: read myprop write myprop;  // direct read/write
property mypropety2: read myprop write prop;  // direct read / indirect write
property mypropety1: read prop write prop; // indeirect read/write
property mypropety2: read myprop;  // direct read only
// .....and more combinations, and you handle types, arrays, and objects too...
}

I guess you'll get "unresolved ambiguity" error: "property = 666" will be
equal to "property(666)", which is ambiguous.

 I like delphi way (more clean):

 class Abc
 {       int myprop;
 void prop(int newproperty) { myprop = newproperty; } // set'er
 int prop() { return myprop; }       // get'er
 property mypropety2: read myprop write myprop;  // direct read/write
 property mypropety2: read myprop write prop;  // direct read / indirect

write
 property mypropety1: read prop write prop; // indeirect read/write
 property mypropety2: read myprop;  // direct read only
 // .....and more combinations, and you handle types, arrays, and objects

too...
 }



class Foo
{
    int prop1;    // simple

    int prop2    // read-only
    {
        get { return 666; }    // gettor
    }

    int prop3
    {
        get { return m_prop3; }
        set { m_prop3 = prop3; }
    }

    private int m_prop3;
}

Yes, is more clean, but if you want multiple properties with same function, how
do it?, example:

class Point
{
private int x;

int getX()  {   return x;  }
void setX(int y) {  x = y; }
bool evalX(int x) { return x > 2; }

property X: read getX write setX; 
property Xgrate2: read getX  write setX stored evalX;   // store eveluate if x
set or not
property XbyStat: read getX  write setX stored evalX default 15;  // set X to
inital value
}

It's not better way, but how do it?, and parses and builders is less difficult

need more work.
