I did not know that, i always separate {} at the beginning | an the end, yet not (). '(' and ')' (parentheses) are operators, '{' and '}' (braces) are not, nor are '[' and ']' (brackets) - though I have never really understood bash's rules for '[[' and ']]' in this context.
`[[' and `]]' are reserved words, and `']]' is recognized as a reserved
word if it appears in a command position, with the provision that after a
`[[', what's between the brackets is a conditional command, with its own
grammar rules, so operators like `;' will cause a parse error.
This is similar to `{' and `}'.
