-%D (Inspired by a discussion on the \CONTEXT\ mailing list)
-%D
-%D In \TEX\ each character can have one of 16 catcodes. This way the
-%D backslash, dollar, ampersand, hash and some more characters get
-%D their  special meaning. If you want to process tokens under a
-%D certain catcode  regime, passing arguments can interfere badly.
-%D
-%D \startbuffer[a]
-%D \def\whatever#1{[#1]}
-%D \whatever{whatever \type {\whatever{you want}} $or$ not!}
-%D \stopbuffer
-%D
-%D \typebuffer[a]
-%D
-%D Here we pass an argument to \type {\whatever} but part of that
-%D argument is to be processed under a different catcode regime, i.e.\
-%D all characters that need to be typeset verbatim need to get
-%D the catcode that makes it a letter. This is what we get when we typeset
-%D the text verbatim:
-%D
-%D \starttyping
-%D whatever \type {\whatever{you want}} $or$ not!
-%D \stoptyping
-%D
-%D However, when passed to \type {\whatever} we get:
-%D
-%D \getbuffer[a]
-%D
-%D In \ETEX\ one can use  \type {\scantokens} to circumvent this problem.
-%D
-%D \startbuffer[b]
-%D \def\rescan#1{\scantokens{#1}}
-%D \def\whatever#1{[\rescan{#1}]}
-%D \whatever{whatever \type {\whatever{you want}} $or$ not!}
-%D \stopbuffer
-%D
-%D \getbuffer[b] \typebuffer[b]
-%D
-%D This time the \type {\whatever} call gives:
-%D
-%D \getbuffer[b]
-%D
-%D In this example, two spaces have crept in. The first one, after the
-%D macro name, is inserted by \TEX\ and cannot be avoided. The last space
-%D is inserted by \type {\scantokens}, and is the consequence of the fact
-%D that this macro mimics reading from a file. You can avoid the last
-%D space by a slightly different definition:
-%D
-%D \startbuffer[c]
-%D \def\rescan#1{\scantokens{#1\ignorespaces}}
-%D \def\whatever#1{[\rescan{#1}]}
-%D \whatever{whatever \type {\whatever{you want}} $or$ not!}
-%D \stopbuffer
-%D
-%D \typebuffer[c]
-%D
-%D Unfortunately we still keep the first space, but at least it's better than
-%D a failure:
-%D
-%D \getbuffer[c]
