% Sometimes one might want to break up a code block into multiple
% pieces, but keep code in different blocks aligned with respect to
% each other. Then one can use the AgdaAlign environment. Example
% usage:
%
% \begin{AgdaAlign}
% \begin{code}
% code
% code (more code)
% \end{code}
% Explanation...
% \begin{code}
% aligned with "code"
% code (aligned with (more code))
% \end{code}
% \end{AgdaAlign}
%
% Note that AgdaAlign environments should not be nested.
%
% Sometimes one might also want to hide code in the middle of a code
% block. This can be accomplished in the following way:
%
% \begin{AgdaAlign}
% \begin{code}
% visible
% \end{code}
% \AgdaHide{
% \begin{code}
% hidden
% \end{code}}
% \begin{code}
% visible
% \end{code}
% \end{AgdaAlign}
%
% However, the result may be ugly: extra space is perhaps inserted
% around the code blocks.
%
% The AgdaSuppressSpace environment ensures that extra space is only
% inserted before the first code block, and after the last one (but
% not if \AgdaNoSpaceAroundCode{} is used).
%
% The environment takes one argument, the number of wrapped code
% blocks (excluding hidden ones). Example usage:
%
% \begin{AgdaAlign}
% \begin{code}
% code
% more code
% \end{code}
% Explanation...
% \begin{AgdaSuppressSpace}{2}
% \begin{code}
% aligned with "code"
% aligned with "more code"
% \end{code}
% \AgdaHide{
% \begin{code}
% hidden code
% \end{code}}
% \begin{code}
% also aligned with "more code"
% \end{code}
% \end{AgdaSuppressSpace}
% \end{AgdaAlign}
%
% Note that AgdaSuppressSpace environments should not be nested.
%
% There is also a combined environment, AgdaMultiCode, that combines
% the effects of AgdaAlign and AgdaSuppressSpace.
