[feature request] comparison operators?

[Mihai Ionescu]

, <, <=, >=, ==, !=

they would be useful for many things, including creating functions like if()

//from ccalc
if(tf,a,b)=(tf!=0)*a+(tf==0)*b

it would be even smoother to have ternary operator like in c++

condition ? a : b

We are planning to add them in #589. The ternary operator is the preferred form so far.
