Is is possible possible to use the default attribute in fn in mojo?

Default attribute? You mean a keyword argument with a default value in a function like this?

fn defaulted_fun(age: Int = 20) -> Int:
    return age * 2

or

def defaulted_def(age = 20):
    return age * 2

if that is what you mean, then no. Keyword arguments with default values are not supported in mojo yet.

Small independent features

There are a number of features that are missing that are important to round out the language fully, but which don’t depend strongly on other features. These include things like:

• Keyword arguments in functions: foo(x=42)

This also applies on the calling side. You can't do this either

fn regular_fn(age: Int) -> Int:
    return age

fn main():
    let doubled = regular_fn(age = 20)  # error here, since keyword args not supported.  uncomment the lines below
    # need to call it without keyword arg
    # let doubled = regular_fn(20)

Thank you so much!
