% Place the argument in matching left/right parntheses.

% Group terms using parentheses.

% Create a set from the given elements
\DeclarePairedDelimiter{\set}{ \lbrace }{ \rbrace }

% A set comprehension, where the ``such that...'' bar is added
% automatically. The bar was chosen over a colon to avoid ambiguity
% with the L : V -> V notation. We can't leverage \set here because \middle
% needs \left and \right present.
\newcommand*{\setc}[2]{ \left\lbrace {#1}\ \middle|\ {#2} \right\rbrace }

% A pair of things.
\DeclarePairedDelimiterX{\pair}[2]{ \lparen }{ \rparen}{ {#1}, {#2} }
