In that spirit I have created a branch bill-nested_braces which changes the
way braces are handled in a backward compatible way.
The outer braces still serves to extend the logical line, but inner braces
will be passed to the parser which will accept
fun(arg1,arg2)={BODY}
as a valid function definition ending at the second brace.

So you can write
{
  my(sinc);
  sinc(x)=
  {
    if(x,sin(x)/x,1)
  };
  fun(a)=
  {
    intnum(x=0,a,sinc(x))
  };
}
parapply(fun,[1..100])

However there is a slight oddity:
fun1()=
{
  print(a);
}; print(b);

and
{
  fun2()=
  {
    print(a);
  }; print(b);
}
will not be parsed the same way:
print(b) belong to fun1() bu tnot to fun2(), instead it belong to the external
block.

Cheers,
Bill.
