Is there a parameterized version of @time where I can suppress output unless e.g. ‘`log_level > k`’ ?

I would like to make the performance of a sequence of function calls debuggable with minimal repetition of code

I am not sure. However, not that there is a `@timed` that outputs nothing but returns the values used to build the output message. You can create a function that takes a Bool, a function name, and the return from `@timed` to conditionally build and output a similar string. So you can call:

```julia
conditional_time(log_level > k, "my_function", @timed my_function(my_args...))

```

If you wanna reduce the repetition of code to a minimal you can use a macro to get the function name without repeating it.

```julia
@conditional_time (log_level > k) my_function(my_args...)

```

`@debug` might be what you want.
