### coexistence of two real_part functions

In Sage 8.8, this code:

```
assume(x, 'complex')
print real_part(x)
print real_part(x).simplify()
```

prints:

```
real_part(x)
realpart(x)
```

This does not change any computation (Sage can prove both are equal), but is annoying, since the second one cannot be copy-pasted back ~~in ~~into the code. The problem is even more visible when `%display latex`

is enabled.

Is this a ~~bug ? ~~bug? Is there a workaround that makes it possible to display beautiful real parts after a ~~simplification ?~~simplification?
