No; this is not part of the Vim syntax.

[Freed-Wu]

vim syntax support shebang. This is a demo:

#!/usr/bin/env vim -u
echo 1

$ chmod +x test.vim
$ ./test.vim
1

[clason]

No, that's not Vim. That's shell.

[Freed-Wu]

See :help #!:

							*:#!*
:#!{anything}		Ignored, so that you can start a Vim script with: >
				#!vim -S
				echo "this is a Vim script"
				quit

That's just a generalized comment marker. Can be added, but low priority.
