Hiram Chirino commented on FELIX-1325:
--------------------------------------
I agree those test cases are kinda invalid. The saddest bit there from a "don't
surprise a unix shell guy" perspective is that ${c} is not the same as $c. Very sad.
I don't know if this is very sad or not. The goal isn't to re-create a
UNIX shell, sometimes you have to break with the past to do something
new. However, I agree it is better to avoid changing unnecessarily if
you can. But I wouldn't want to put undue pressure on the project to try
to be like a UNIX shell when it doesn't fit.
And believe it or not, not everyone is intimately familiar with UNIX
shells. :-)

But on related note... to the gogo developers: I would have expected a
command not found error when you type in a command that's not found. This
seems to work fine if you pass an argument to a command. It this a
'feature' or a bug?
This is a 'feature', in that an undefined command silently returns itself,
rather than an error.
This is so that:
x = hello
works; otherwise the assignment would fail, with a command not found error.
Note: that
x = hello world
will actually evaluate the 'hello' command with 'world' as an argument.
x = "hello world"
tries to evaulate the 'hello world' command, which probably doesn't exist, so
it falls back to returning the value, rather than unknown command.
I think this can be simply resolved by avoiding re-evaluating an assignment
with a single argument.
This will mean that
x = hello
works as it does currently, but that
hello
will fail with 'unknown command', rather than simply return itself.
