Block comments on a single line cause syntax errors

[kjmahalingam]

Block comments are typically meant to be used as multi-line comments, such as this:

/*
Comment
Comment
/*

Using a block comment on a single line like below causes a syntax error:

/* Comment Comment */

Although it is unlikely that this will be an issue, since we have support natively for single-line comment syntax with //, this is an unintended error and should be resolved.
