The example code given in the REPL help uses let, which causes it to fail. See :mojo help repl
Steps to reproduce
Welcome to Mojo! 🔥
Expressions are delimited by a blank line.
Type `:quit` to exit the REPL and `:mojo help` for further assistance.
1> :mojo help repl
The Mojo REPL (Read-Eval-Print-Loop) acts like an
interpreter of Mojo expressions, which are delimited by a
blank line. These expressions can define top-level
variables, functions, structs, and other declarations, which
are persisted across expressions. For example:
1> let my_var = "Welcome to Mojo!"
2.
2> print(my_var)
3.
Welcome to Mojo!
Besides that, it is possible to execute Python expressions
using the %%python magic, which offers seamless interop with
Mojo code, including exposing top-level python declarations
in subsequent Mojo expressions. For example:
1> %%python
2> import sys
3> print("Python version from python:", sys.version)
4.
Python version from python: 3.11.4
5> print("Python version from Mojo:", sys.version)
6.
Python version from Mojo: 3.11.4
As the Mojo REPL is based on LLDB, the complete set of LLDB
debugging commands is also available as described below.
Commands must be prefixed with a colon at the REPL prompt
(:quit for example).
Typing just a colon followed by return will switch to the
LLDB prompt.
Type "< path" to read in code from a text file "path".
Finally, we encourage you to submit feature requests and error reports in
https://github.com/modularml/mojo/issues.
