reverseArgs

Example

alias gt = reverseArgs!(binaryFun!("a < b"));
assert(gt(2, 1) && !gt(1, 1));

Example

int x = 42;
bool xyz(int a, int b) { return a * x < b / x; }
auto foo = &xyz;
foo(4, 5);
alias zyx = reverseArgs!(foo);
writeln(zyx(5, 4)); // foo(4, 5)

Example

alias gt = reverseArgs!(binaryFun!("a < b"));
assert(gt(2, 1) && !gt(1, 1));
int x = 42;
bool xyz(int a, int b) { return a * x < b / x; }
auto foo = &xyz;
foo(4, 5);
alias zyx = reverseArgs!(foo);
writeln(zyx(5, 4)); // foo(4, 5)

Example

int abc(int a, int b, int c) { return a * b + c; }
alias cba = reverseArgs!abc;
writeln(abc(91, 17, 32)); // cba(32, 17, 91)

Example

int a(int a) { return a * 2; }
alias _a = reverseArgs!a;
writeln(a(2)); // _a(2)

Example

int b() { return 4; }
alias _b = reverseArgs!b;
writeln(b()); // _b()
