The new pragmats are introduced as an addition to the existing pragmats, requiring rather straightforward changes to the lexical analyzer.
It is recommended for implementations offering stropping regimes based on reserved words to only recognize pragmats with symmetric delimiters, and of these only the brief style.
Since pragmats can be concatenated, it is advisable to compilers to use a pragmat language in which such concatenation will lead to a valid sequence of orders.
