General ⇒ Question about brackets in newcommand

[dmt]

What is the difference between the following two uses of \newcommand?

Code: Select all

\newcommand\foo{stuff}

and

Code: Select all

\newcommand{\foo}{stuff}

I didn't think there was any difference, but I have noticed some odd spacing irregularities in some cases.

There is no difference between both uses of \newcommand. The irregularities you notice will surely have a different cause. Post here some example.

Wow, I must have had some weird typo before since I am now unable to reproduce the problem. Thanks for the answer anyway. Good to know for the future.
