How about nested curly braces, like {INSERTANS:{SGQ}}?
This example has escaped curly braces like \{this is not an equation\}
Should the parser check for unmatched { opening curly braces?
What about for unmatched } closing curly braces?
What if there is a { space after the opening brace?}
What about a {space before the closing brace }?
What about an { expression nested {within a string} that has white space after the opening brace}?
This {expression has {a nested curly brace { plus ones with whitespace around them} - they should be properly captured} into an expression with sub-expressions.
This {is a string {since it does not close } all of its curly} braces.
Can {expressions contain 'single' or "double" quoted strings}?
Can an expression contain a perl regular expression like this {'/^\d{3}-\d{2}-\d{4}$/'}?

{name}, you said that you are {age} years old, and that you have {numKids} {if((numKids==1),'child','children')} and {numPets} {if((numPets==1),'pet','pets')} running around the house. So, you have {numKids + numPets} wild {if((numKids + numPets ==1),'beast','beasts')} to chase around every day.
Since you have more {if((INSERT61764X1X3 > INSERT61764X1X4),'children','pets')} than you do {if((INSERT61764X1X3 > INSERT61764X1X4),'pets','children')}, do you feel that the {if((INSERT61764X1X3 > INSERT61764X1X4),'pets','children')} are at a disadvantage?
