Our build process requires no space between closing } and ) for variable modules (i.e. those with paths containing /var/). This makes it impossible to follow our style guide and write those modules in this way:

define( function() {
    /* code */
} );

instead of currently required:

define( function() {
    /* code */
} );

There may be other cases like that in used regexes.

I'll assign this to @timmywil since it's his code. I hope you don't mind, Timmy. :-)
