We type the following foo(10, default, default, default, 12, default) But the IDE shows it as foo(*param1:* 10, *param2:* default, *param3:* default, *param4:* default, * param5:* 12); This is similar to IDE using a special character to show spaces, tabs & newlines.

The IDE showing names doesn't help much.=A0 The difference is:

foo(10, default, default, default, 12, default)
vs
foo(.x =3D 10, .z =3D 12)

Some people = might find the second easier to read and understand.=A0 (And some might pre= fer the first because it doesn't "hide" as much.)

By IDE showing nam= es I meant this. We type the following
foo(10, default, def= ault, default, 12, default)
But the IDE shows it as
foo(param1: 10, param2: default, = param3: default, param4: default, param5: 12);

This is similar to IDE usin= g a special character to show spaces, tabs & newlines. I don't see = any difference between IDE doing this and we doing it. The existing code al= so works with this. We need not have a language feature which can be done b= etter by the IDE. I agree that it will not work with other general purpose = editors. Other than that is there any use of named parameters?
